Power, Precision and Performance: Selecting Batch Plants for UHPC

Ultra-High-Performance Concrete (UHPC) is an advanced class of concrete known for its exceptional strength, durability and resilience compared to conventional mixes. UHPC boasts compressive strengths above 22,000 psi (150 MPa), more than double the performance of high-strength concrete.

UHPC is dense and impermeable, thanks to a mix-design that includes fine powders such as silica fume and quartz flour, a very low water-to-cement ratio, high range-water reducers, and steel or polymer fibers. So, it may come as no surprise that UHPC producers require a specialized approach when investing in mixing technology and batch plants.

In this article, Mixer Systems, Inc., experts weigh in on the unique specifications and options producers should consider when UHPC production demands power, precision and performance.

High Shear Mixing Technology

At the heart of UHPC production is high shear mixing technology. Because UHPC is typically used in large infrastructure and complex architectural applications, high volume is an important factor as well. Traditional drum mixers simply cannot provide the energy or precision required to thoroughly combine dry powders with water and superplasticizers, or to evenly disperse fibers throughout the mix. Furthermore, traditional drum mixers or concrete mixing trucks producing UHPC can be very difficult to clean, making it an undesirable product to supply.

Planetary mixers, horizontal shaft and twin shaft mixers are the most common mixers used to mix UHPC. Planetary mixers from Mixer Systems, Inc. produce a unique counter current mixing action, resulting in fast, homogenous mixes. Horizontal mixers from Mixer Systems, Inc. are typically used on smaller applications, including on-site UHPC production.

Mixer Systems, Inc., Twin Shaft mixers are high volume, high shear with mixing times from 60-90 seconds. Intermeshing paddles to rapidly blend materials while maintaining consistent flow and distribution and have been successfully used on major UHPC projects such as the Delaware Memorial Bridge resurfacing project.

High-shear energy is especially important during the addition of water and superplasticizers. The extremely low water content of UHPC means that even slight inconsistencies can lead to clumping, reduced workability, or strength losses.

Advanced mixers often incorporate variable speed controls and multiple mixing phases – dry blending, liquid introduction and high-energy homogenization – to achieve the required paste fluidity and particle dispersion. All of these systems can be equipped with automatic washout systems making maintenance significantly easier.

Batch Plant Automation and Accuracy

Beyond the mixer itself, the batch plant plays a vital role in successful UHPC production. Precision is paramount at every step, from weighing powders to testing aggregate moisture. UHPC mix designs have small tolerances compared to conventional concrete, and errors in batching can have serious impacts on performance and can be very costly.

UHPC producers should look for batch plants that provide:

• Automated powder handling systems for cement, silica fume and quartz powder.
• High accuracy weighing systems capable of handling fine powders and micro-additions.
• Specialized liquid dosing equipment for superplasticizers and other admixtures that must be delivered within tight tolerances.
• Fiber feeders that meter and introduce steel or polymer fibers without clumping.
• Temperature control to manage heat generated from mixing, including a cooling system or chilled water dosing.

The BatchMaster plant from Mixer Systems, Inc., is a top-of-the-line plant capable of producing up to 250 yards per hour. Mixer Systems load cells feature an aggregate weighing accuracy within +/-2% and cement/water weighing accuracy within +/-1% of the batch size. Proprietary automated controls run a high-volume batch plant from start to finish-batching, mixing, moisture control, even automated concrete delivery of different mix designs to multiple locations.

The Path to Scalable UHPC Production

As demand for UHPC grows in infrastructure, precast, and architectural applications, the importance of advanced mixing and batching systems will only increase. High-shear mixers and precisely engineered batch plants are essential to unlocking the full potential of this specialty mix.

Mixer Systems, Inc., pours more than 45 years of experience into the design, manufacturing and construction of every mixer system we produce. We build every mixer, batch plant and batch control system from the ground up to meet customer specifications.

For producers, investment in the right equipment enables not only superior material quality but also improved efficiency and repeatability, ensuring UHPC can be scaled to meet the needs of tomorrow’s most ambitious projects.

When you’re landlocked on just 3.5 acres in the middle of a residential neighborhood, expanding your concrete operation to increase output isn’t an option. For Zeiser Precast, a long-standing precast concrete producer in Elmira, New York, the challenge was clear: how to significantly increase daily concrete yield without adding a single square foot. 

Their solution? Upgrade to a larger mixer within the same footprint. 

Ready for an Upgrade 

Zeiser has been producing precast concrete since its establishment in 1946 as Zeiser Wilbert Vault, Inc. From burial vaults to retaining wall blocks, manholes, and septic tanks, their product line and customer base have expanded, while their production space remained fixed.  

Since the 1980s, Zeiser’s concrete was mixed with a Mixer Systems, Inc., Model 30 Horizontal Shaft. In 2008, Zeiser replaced the Mixer Systems E-100 batch control system that was over 20 years old with a touchscreen automation system from a different manufacturer that provided the features they needed. By 2024, the third party control system, which was running on outdated Windows 98 software, was failing and prone to glitches.  

“We’d been struggling with the failing operating system for the last couple of years,” said Stephanie Risley, president and second-generation owner. “We could no longer operate as we were, it was costing us a lot of time and money.” 

At the same time, demand for Zeiser’s precast and specialty products was outpacing their production capabilities. That’s when they turned back to a trusted partner: Mixer Systems, Inc. 

Same Space, Bigger Capacity 

Zeiser had relied on Mixer Systems for more than 40 years, so when the opportunity came to upgrade both the control system and the mixer, the decision was easy. The existing mixer was a Model 30 Horizontal Shaft Mixer with a 1-yard input capacity.  

“We decided it would be a good idea to increase our capacity and upgrade our operating system at the same time,” Risley said. “We are planning for our future and wanted to be ready for our next phase.” 

The upgrade to a Model 54 Horizontal Shaft Mixer, which has a 2-yard capacity, doubled the potential production for Zeiser. With their current production schedule, the increased capacity allowed the Zeiser team to immediately boost their yield by 50% per batch. 

What made this project stand out was that Mixer Systems helped fit the entire upgrade within the same production footprint. No structural expansion, no additional land needed. Just smarter, more efficient equipment designed to work harder in the same space. 

“Our plant is surrounded by homes, churches, schools. We can’t expand,” said Jeremy Sherman, general manager for Zeiser Precast. “So, we had to get creative. The Mixer team worked closely with us to design a system that would maximize every square foot.” 

Operational Payoff 

The new mixer, powered by Mixer Systems E-150 Batch Control system, transformed operations. Batching is now faster, more consistent, and less labor-intensive. 

“The decision to replace the operating system alone was a lifesaver,” Sherman said. “We struggled to produce a well-designed batch on a daily basis because the software was so old.” 

The E-150 Batch Control System was designed with growth in mind. Based around a 22” high-definition, industrial touchscreen display, the E-150 is powered by a PLC/PC hybrid computer system housed in a NEMA 4 wall mountable enclosure that is adaptable to most concrete batch plants currently in operation.  

“It was amazing how quickly things improved,” said Sherman. “After just three trial batches, we saw a difference. We’re producing more yards at a faster rate and more consistently, and our team is going home earlier. That’s a big deal for us.” 

Additional features include full simulation mode, printable plant schematics and electronic drawings, highly accurate slump and yield control, automatic and manual batching modes, online access for remote diagnostics of mechanical and electrical plant issues, a dedicated Mixer Systems service staff, and more.  

“Zeiser was excellent to work with, very accommodating and open to discussing their long-term growth plans so we could ensure they had the right solution now and into the future,” said Jonathan Jaruseski, National Sales Manager for Mixer Systems, Inc. 

A Future-Proof Investment 

From improved batching speed to reduced software headaches, Zeiser’s new Mixer Systems mixer proved to be a sound investment with immediate returns. 

“We were shut down for about a month for the install,” Risley said. “When Mixer Systems got our new system online it was so exciting, it’s been about 6 months and the new mixer and operating system have been flawless.”  

Whether producing burial vaults, catch basins, septic tanks, or custom solutions, Zeiser now operates with the confidence that their plant is designed to handle the demands of modern precast production, without needing more space to do it. 

The Model 54 Horizontal Shaft is the same footprint as the Model 30 Zeiser was already using, the installation team just needed to accommodate for additional height.  

“We’ve never had a quality issue with anything from Mixer Systems and this upgrade was no exception,” Sherman said. “It exceeded expectations.” 

Zeiser employs a team of 35 employees, with 30 on the production and dry side. Yet they produce a wide variety of precast products, many made to order, some kept in inventory. Increasing output without increasing hours has not only improved productivity but also strengthened employee satisfaction. 

“We’re a family-oriented company,” Sherman said. “If our team can work efficiently and still have time with their families, that’s a win. This upgrade gave us that and more.” 

In foundry operations, the quality of green sand means the difference between producing reliable, defect-free castings and facing costly rework or scrap. Every mold’s performance and every casting’s integrity depends on the consistency, strength, and permeability of its sand.

First, each grain of sand needs to be evenly coated with clay binder and moisture. Well-prepared sand packs uniformly, giving the mold enough strength to hold its shape during pouring. This also controls permeability, allowing gases to escape without letting metal steep through.

A dialed-in preparation process creates predictable results from mold to mold, which is essential for meeting tolerances and surface finish requirements.

Mulling machines are an ideal piece of foundry equipment for the initial preparation of sand and to condition it for reuse in making molds.

Mulling machines help achieve ideal green sand quality by doing three critical things at once:

1. Kneading and coating the sand grains – Heavy muller wheels press and shear the sand, forcing the clay binder and moisture to wrap evenly around every grain. This creates uniform bonding strength so the mold can hold its shape without weak spots.
2. Breaking up clumps and blending additives – Any lumps of sand, dried clay, or leftover additives are crushed and dispersed. New sand, reclaimed sand, bentonite, sea coal, and other additives are blended into a perfectly consistent mix, preventing areas of the mold from behaving differently during pouring.
3. Controlling moisture and plasticity – The mulling process evenly distributes water through the sand, preventing soggy spots and dry patches. This ensures consistent compaction, so the mold surface is smooth, strong, and has the right permeability for gases to escape.

Mulling isn’t just mixing, it’s conditioning the sand, so it behaves the same way every time, which is exactly what a foundry needs for consistent casting quality.

Following are the differences between poorly prepared sand and properly mulled sand:

While mulling machines are critical to operations, historically, foundries have had limited equipment options. The SandMASTER Muller Mixer from Mixer Systems, Inc., leverages a simplified compaction technology that was designed specifically for foundry sand preparation.

Five mixing paddles are fixed on a counter-rotating start for fast, thorough blending that is consistent across all batches.

Top-mounted drive and access doors provide easy maintenance without the need to dissemble the mixer.

An innovative Sand Wedge compaction technology replaces rollers for cleaner, more efficient mulling.

And a liner wall scraper follow the Sand Wedge to gather compacted sand and push it toward the mixer bottom.

The quality of a casting is directly tied to the quality of mold it was poured in. Mulling machines condition green sand to ensure uniform binder coating, consistent moisture, and proper compaction. The simplified and innovative SandMASTER mulling mixer helps foundries produce molds that perform reliably under the extreme demands of metal casting. The payoff is clear: reduced scrap rates, improved surface finishes, and repeatable quality with every pour.

Unlocking Better Concrete with Sequencing and Automation

In the world of concrete production, consistency is everything. Whether you are pouring a few yards a day or hundreds, the performance of the final product hinges on the precise sequencing of ingredients during batching. Stone, sand, admixtures, cement and water must be introduced into the mixer in a specific order, and that sequence is far from arbitrary. Done incorrectly, it can drastically impact the strength, finish and performance of the final product.

At Mixer Systems, Inc., we understand the complexity and science behind batching. That’s why we’ve designed our equipment and automation systems to bring precision and repeatability to every batch at any scale. As a one-stop shop, we supply everything, from mixers and complete batch plants to mixer and batch controls, material handling systems and wash down systems. There’s no need to coordinate multiple vendors because we streamline the entire operation for our customers.

Mix Order Matters

The sequence of introducing materialslike stone, sand, admixtures, cement and water affects not just how the mix performs, but also how efficiently the equipment runs. Variables like mixer style, speed, accuracy of the amount being batched, yardage, and admixture types (including superplasticizers, densifiers, or self-consolidating concrete mixes) all influence the required order of operations.

For example, stone is typically added first to allow the voids to fill with the finer materials and help prevent buildup. Sand follows, often making up 60–80% of the aggregate if a customer is following industry standards with their mix design. A small amount of pre-wet may be introduced next, precisely timed to avoid premature cement hydration or pooling in the aggregate. Cement and admixtures are added afterward, using timers for accuracy. This controlled, sequenced approach ensures that materials blend properly and the admixtures perform as designed.

Common Issues

When materials are added out of sequence or in incorrect proportions, issues like spalling, balling, or inconsistent setting can occur. For example, adding admixtures too early or too late in the main water sequence can prevent them from dispersing properly which can weaken the mix or alter its intended characteristics.

Timing errors also impact the functionality of chemical additives. Superplasticizers, for instance, are meant to enhance flowability over time, but if added incorrectly, they can cause the mix to separate or remain too fluid. Accelerators added too early can create a lumpy or granola-like texture.

Tail water, which is leftover water from the mix, can further complicate matters, preventing the formation of a smooth, homogeneous blend. These small missteps, if left uncorrected, can significantly degrade the strength, workability and finish of the final product.

Environmental conditions also play a critical role in batch control. Pre-wetting aggregates is key to achieving consistent moisture content, especially in environments that are overly humid or dry. Without the right moisture level, cementitious binders may not hydrate properly, leading to performance issues.

Accurate batch control is essential in concrete mixing to ensure consistent performance and durability.

Automation systems are designed to precisely control when and how much of each material is introduced, preventing errors that may not be visible until the final product fails in the field.

Automated Batching for Repeatable Results

Batching is as much about order and timing as it is about consistency. Mixer Systems, Inc. is one of the few manufacturers that builds its own batch plant controls in-house. This gives us the unique ability to tailor the entire system to each customer’s mixer, production needs and preferred mix designs. Other manufacturers often outsource these controls, which runs the risk of inefficiencies and miscommunication.

Our batch plant automation is designed to repeat the exact same sequence throughout the production day, allowing customers to replicate performance across dozens or even hundreds of batches. Full simulation mode allows batch operators to gain experience by batching their mix designs in real-time without actually using cement and aggregate materials.

Each system includes:

• Pre-programmed timers for sequencing ingredient drops
• Weight-based batching for cement and aggregate
• Moisture compensation using bin probes and water meters
• Adjustable mix times based on current draw and mix type

Precision matters even more for specialized mixes like self-consolidating concrete, where delayed chemical introduction is critical. With automated batching, customers can program secondary timers to ensure the admixture is only released after the main water is added.

The Water Quotient

A precise water-to-cement ratio is a must, which requires an understanding not only of how much water to add to a mix, but how much is already contained within the aggregate. The correct water-to-cement ratio will also help indicate when a mix is complete.

Aggregate moisture levels can vary significantly depending on where material is sourced from within the stockpile and how long materials are sitting in bins. Different moisture levels arise due to the natural settling of water. Environmental conditions such as rain and humidity also play a part. Bin probes and water meters from Mixer Systems, Inc., provide real-time readings of moisture levels so that water and material are both considered when adding an ingredient to a mix. This ensures proper sequencing and yield.

Once in the mixer, Mixer Systems, Inc., relies on a wattmeter to monitor a mix and understand when it is complete. The wattmeter measures how hard the mixer motor is working. When there is less water, it requires more power to mix. As water and admixtures are added during the order of mixing, the motor will require less power. Once the wattmeter shows the motor is working at the target power percentage, as an example, 40%, the operator will receive a mix complete signal.

Testing Makes Perfect

While we do not create mix designs for customers, we strongly emphasize the importance of thorough testing when developing a concrete mix. Admixtures play a critical role in achieving durability, sustainability, and workability, but their performance can vary depending on many factors. That’s why product testing is essential—to confirm that each component interacts as expected within the desired performance parameters. Partnering with admixture suppliers who understand both product chemistry and environmental considerations can help identify opportunities for improving the mix through trial, testing and adjustment.

One of the key factors in mix behavior is the nature of the aggregates. Our aggregate supply is based on the Fineness Modulus (FM), which measures how fine or coarse the material is. Depending on the customer’s original mix, adapting it to our FM values can require careful adjustment. For example, we’ve seen issues such as slurry balling when using quartz aggregates that couldn’t absorb enough moisture to properly disperse. In contrast, our usual materials, including sand, stone, and fly ash, have established performance characteristics that support a predictable batching and mixing process. But even with familiar ingredients, testing is still necessary to ensure consistency and repeatability.

Geographic and environmental conditions also affect concrete performance, which is why localized testing is so important. For example, mixes must be tailored to withstand challenges like freeze-thaw cycles in regions such as the Midwest, where frost balls can affect mix integrity. Working with admixture partners who understand these regional variables allows for better planning and performance. Regular testing such as strength breaks and monitoring for issues like inconsistent test strengths can reveal problems early, such as equipment malfunctions like a leaking gate. Ultimately, dialing in a reliable mix is a process of trial, testing and refinement.

Selecting the Best Mixer for the Job

Selecting the right concrete mixer is critical to achieving consistent quality, efficiency, and performance, especially when production volume and mix design requirements vary. Different mixes, such as those with high-flow admixtures, low-slump materials, or specialty aggregates, demand specific levels of agitation and batch control.

High-production environments often benefit from twin-shaft mixers, which offer intense shear and fast mixing cycles, while smaller batches or intricate mix designs may be better suited for planetary or pan mixers. Choosing the wrong mixer can lead to inconsistent blending, longer cycle times, and even material waste, especially when dealing with complex or sensitive formulas.

Additionally, pooling is more likely in horizontal or turbine-style mixers, which offer less agitation compared to planetary or twin-shaft mixers. This makes precise control over material addition even more important in those systems to avoid uneven distribution and ensure a reliable mix every time.

Ready-Mix Concrete vs. Batch Plant Investment: Which is Right for Your Business? 

When it comes to sourcing concrete for construction or manufacturing, contractors and business owners typically face two options: ordering ready-mix from a local production facility or investing in their own batch plant. Each choice carries distinct advantages, costs, and risks. Understanding the key differences can help you make the best decision for your operation. 

Ready-Mix Delivery: Third-Party Dependence 

Ready-mix concrete is produced off-site at a central batching facility and delivered to job sites or facility locations via mixer trucks. Ready-mix providers handle raw material procurement, quality control, environmental compliance, and delivery logistics. With no need for upfront capital investment or dedicated staffing, ready-mix can be the go-to choice for short-term projects, variable production demand, or lower annual volume demand. 

The cost of using a third party for concrete delivery is two-fold. First, is unpredictable delivery scheduling. Most of the time, ready-mix plants are producing concrete for a variety of customers at the same time. Sometimes a pre-caster who relies on ready-mix has to wait longer than expected for a delivery, which in turn impacts their own production schedule and goals. Second, the per yard cost can total more than $150/yard especially when delivery fees and waiting charges are included.  

For manufacturers who produce concrete-based products such as underground utilities, culverts, septic tanks, structural elements, and infrastructure products, a ready-mix order could easily equal 100 yards per day or more, costing $15,000 per day. Owning a batch plant may be a more cost-effective option and it eliminates access to concrete as a constraint. 

Batch Plant Ownership: Control and Cost Efficiency 

For operations requiring large volumes of concrete—such as pre-casters serving the burial, infrastructure, and waste management industries —investing in a batch plant can lead to significant long-term savings. By producing concrete on-site, companies reduce transportation costs, gain full control over production schedules, and can adjust mix designs in real time. 

Owning a batch plant comes with an increase in responsibility compared to a ready-mix delivery service. Start-up costs can exceed $200,000, not including land, utilities, and permitting. Ongoing expenses include staffing, maintenance, material sourcing, and regulatory compliance. But once it is up and running, a batch plant will reduce the cost per yard for concrete from an estimated $150/yard to $80/yard. 

Mixer Systems Inc. prides itself on being a one-stop resource. We provide advanced product planning, offer state-of-the-art manufacturing, and design and construct concrete batch plants from the ground up.

Mixer Systems experts are available for any batch system support your team needs, including training, troubleshooting, servicing, and shipping parts within 24 hours. Explore all of our batch system products in our Buyers Guide. 

Choosing the Right Option 

The break-even volume—the point where a batch plant becomes more cost-effective than ready-mix deliveries—varies by region and costs, but generally falls around 25 cubic yards per day. Business owners expecting lower annual volume and can establish a reliable relationship with a ready mix company could find ready mix a reasonable option. Those with limited scheduling flexibility, higher-volume needs, the capacity to manage production, and the need to control costs may benefit from batch plant ownership. 

By carefully evaluating costs, logistics, and operational demands, you can choose the most efficient and profitable concrete sourcing strategy.

When it comes to concrete production, the efficiency, scalability, and customization of your batching system can significantly impact your bottom line.  

 Mixer Systems, Inc., has been a leader in designing and manufacturing mixers and batch plants for more than 45 years. In this guide, we’ll walk you through the key differences between Mixer Systems batch plant products so you can find the perfect fit for your operation.  

 First, let’s cover the basics of what a concrete batch plant is and how it works.  

 A concrete batch plant, also known as a concrete mixing plant or batching plant, is a facility where the ingredients of concrete—such as cement, water, sand, aggregates, and admixtures—are precisely combined to produce concrete. These plants are designed for efficiency, accuracy, and consistency to ensure high-quality concrete for construction projects. 

How a Concrete Batch Plant Works 

Concrete batching involves a series of carefully controlled steps. Here’s a breakdown of the process: 

1. Material Storage

The raw materials—cement, sand, gravel (aggregates), water, and additives—are stored in separate containers: 

• Cement silos store cement and fly ash. 

• Aggregate bins hold sand and various sizes of gravel. 

• Water tanks supply clean water. 

• Admixture tanks store chemical additives used to modify the properties of the concrete.

2. Weighing and Measuring 

Accuracy in proportions is crucial for quality control. Each component is measured by weight using load cells and scales: 

• Aggregates are weighed on conveyor belts or in hoppers. 

• Cement is weighed using screw conveyors or gravity-fed hoppers. 

• Water and admixtures are measured with flow meters or scales. 

3. Mixing Process 

The measured materials are transferred to the mixing unit. Mixers can be of various types, including horizontal shaft, turbin, planetary, and twin shaft, each offering different mixing speeds and qualities. 

 4. Loading and Delivery 

Once mixed, the concrete is discharged directly to a production line or construction site with a skip hoist, a conveyor, a monorail transport bucket, or an overhead crane bucket.  

A concrete batch plant provides consistency through automated systems that ensure uniform quality. They are also efficient, producing large volumes of concrete quickly. Batch plant and mixer designs can be adjusted to meet specific project needs and controlled batching minimizes material waste.  

 Every batch plant from Mixer Systems is custom designed, manufactured and installed to meet a customer’s exact specifications for capacity and performance. Concrete producers choose a batch plant and one of four different mixers to handle production requirements for consistently high quality wet or dry mixes. Mixer also provides silos, hoppers and other components from a single source.

Quality Tip: How to Avoid Excessive & Uncompensated Moisture in a Concrete Batch Plant

The most important part of a concrete mix design is the water-to-cement ratio. The ratio is the amount of water to the quantity of cement, typically both measured in pounds. This ratio is important for creating enough cement paste to be able to bind all of the other materials together. The materials in a concrete batch include stone, sand, cementitious powder and water. More complex mixes could include non-cementitious powders, admixtures, and fibers.

When the materials are used wet – above saturated surface dry (SSD) weight – the water in the material is included in the weight of material. For example, if your material has 5% moisture above SSD weight and you batch 1,000 lbs. of this material, you will have 50 lbs. of extra water and you will have only 950 lbs. of material. This affects two parts of the batch. First, it will result in 6 gal of extra water. Second, it will reduce the yield. This wastes cement because more cement is added than needed to paste a smaller amount of material together.

Excessive moisture can result in:

• Overly wet mixes: Too much moisture can make the mix too fluid, reducing strength and leading to segregation of material.
• Inconsistent strength: Variations in aggregate moisture cause fluctuations in mix proportions, leading to unpredictable compressive strength.
• Extended setting times: Higher water content can delay curing and setting, impacting production schedules.
• Surface defects: Excess moisture can lead to problems like scaling, cracking and poor finish quality.

Understand Stockpile Moisture Variations
Aggregate moisture levels can vary significantly depending on where material is sourced from within the stockpile. Different moisture levels arise due to the natural settling of water in the pile, particularly in rainy or humid conditions. Trucks may pick up materials from different sections of the quarry’s stockpiles, which will also affect the moisture content in the batch.

The loading of the bins should be done as close to the start of batching as possible, as this timing will make for more consistent moisture readings from probe. The longer the materials sit in the bins the more water drains to the bottom of the aggregate.

To mitigate the risk of excess moisture:

• Equipment operators should avoid taking aggregates from the bottom of the pile, as this area tends to retain more moisture.
• Operators should keep the bucket level at least 18” to 24” from the bottom of the pile.
• Whenever possible, aggregates should be taken from higher points in the stockpile where moisture levels are lower and more consistent.
• Frequently stir up the pile to redistribute the moisture in the pile.
• In rainy weather or hot weather covering the pile will keep the moisture in the pile more consistent.

By ensuring proper loading and stockpile protection practices, concrete producers can significantly reduce variations in moisture content and enhance mix consistency.

Regularly Test for Yield Compensation
Regular testing of aggregate content and proper stockpile management are necessary to ensure a consistent and high-quality concrete mix.

The frequency of testing depends on whether the plant has moisture probes installed.

• For plants with moisture probes installed: Testing should be conducted at least once a week to ensure proper probe calibration.
• For plants without moisture probes: More frequent testing is necessary, with moisture checks performed in the morning, late morning and mid-afternoon before the shift ends.

This routine helps maintain an accurate water-to-cement ratio and your yield, reducing the risk of excess moisture that can compromise your concrete’s performance.

Incorporate Moisture Burn off Testing into Daily Procedures
To improve overall product quality, it is important to formally integrate burn off tests into your plant’s daily operating procedures which includes; accurate material moisture testing, taking samples, weighing and the drying of the samples. Standardizing this procedure will ensure all team members will remain vigilant about moisture fluctuations and take corrective actions when needed.

By adopting these proactive strategies, concrete producers can prevent excess moisture and correct yields leading to a more reliable and durable final product. A well-maintained quality control process not only enhances product integrity but also minimizes costly labor, rework and material waste. Staying ahead of moisture-related challenges will contribute to a more efficient and successful concrete batching operation.

Nestled in Kingston in upstate New York, LHV Precast thrives as a leading producer of precast concrete materials, catering to diverse project needs while continually exploring new opportunities. Founded in 1979 by Dick and Clarice Willis, the family-owned enterprise evolved from a modest setup with a trailer, a phone, and a boom truck into a comprehensive operation offering an extensive range of products. Their lineup includes catch basins, manholes, electrical vaults, light pole bases, box culverts, three-sided spans, retaining walls, and custom solutions tailored to specific project requirements.

Jim and Bob Willis, the founders’ sons, grew up working in the plant but left to attend college. Returning home to help with the family business, today, Jim and Bob manage the plant, grooming the next generation to follow in their footsteps.

The company attributes its success from the Willis’ commitment to innovation and fostering strong partnerships with reliable suppliers. Mixer Systems, Inc., has been a key partner since the early 1980s, supplying mixers, accessories, and a complete batch plant. When LHV Precast’s old Prashak horizontal mixer, purchased in the early 1960s, needed to be replaced, Jim began looking for options. His visits to nearby plants highlighted the difficulties of sourcing foreign parts and having American-made equipment became a priority.

“When we were initially putting the plant together, we visited a few companies nearby to look at equipment, and they were having trouble getting foreign parts. It was at that moment we decided it needs to be made in America,” Jim explains. “We have had a relationship with Mixer Systems ever since.”

“In 1986, LHV Precast invested in their first Turbin Mixer from Mixer Systems, marking the beginning of our partnership,” according to Mixer Sales Manager Jonathan Jaruseski. After pouring over 400,000 yards of concrete over 35 years, the mixer is now retired and headed back to the Mixer Systems’ facility in Pewaukee to be put on display.

“When the time came to replace the mixer, there was no hesitation—Mixer Systems was our first choice,” Jim affirms. “Their products are backed by top-notch engineering and technical support, essential for our operations.”

In May 2021, LHV Precast began an ambitious project to expand its operations by constructing a state-of-the-art facility. This endeavor was carried out in collaboration with Mixer Systems and Emil Garlewicz of Concrete Plants, Inc., whose expertise was instrumental in shaping the new plant. “Emil Garlewicz, who recently passed away, was highly valued by Mixer Systems, as was his entire team at Concrete Plants, Inc.,” says Jaruseski. ‘’It was a smooth process with all of us working together to make sure LHV’s plant was exactly the way they envisioned.”

The expansion project included adding 21,600 square feet to the existing 14,400-square-foot building. The upgraded facility now features advanced components, including a new batch plant and additional aggregate and admixture silos, enhancing its production capabilities and efficiency.

“Mixer Systems was the logical choice to partner with on this project,” Emil stated. “Not only do they have some of the finest equipment available in the United States, they have the service and expertise to work alongside us.” The new facility includes a dedicated 3.5-cubic-yard batch plant with a Turbin Mixer from Mixer Systems. This setup includes a computerized washout, designed to streamline the cleaning process.

“The new facility, commissioned in February 2022 after rigorous certifications, underscores our commitment to growth,” says John Klassen, LHV Precasts’ CFO. “Our partnership with Mixer Systems is more than just transactional—it’s a collaborative effort where troubleshooting and support are readily available. There is always someone at Mixer that can assist with troubleshooting.”

“We want to keep growing the business,” Jim adds. “We are always looking for another product line, or another solution to offer. Because when it comes right down to it, people know the skill that we bring to projects, and we are in a good position to keep doing what we do.”
