Shrinkage-Compensating Concrete Eliminates Control Joints in Food Processing Facility Expansion

The Sugar Creek food processing facility expansion stands as a compelling case study in the application of advanced concrete technology to solve real-world construction challenges. By addressing the fundamental material science of drying shrinkage, the project team delivered a floor system that meets the stringent demands of food processing while reducing construction complexity and long-term maintenance. As the construction industry continues to demand higher performance from concrete floor systems, Type K shrinkage-compensating concrete offers a proven solution that deserves broader consideration.

1. Evaluate shrinkage-compensating concrete early. For projects where joint reduction, crack control, or hygiene requirements are critical, Type K systems should be considered during the conceptual design phase rather than as a value engineering substitute.
2. Plan for adequate curing. Type K concrete requires a minimum seven-day wet curing period. Project schedules must accommodate this requirement, and contingency plans should address cold weather or low-humidity conditions that could affect curing.
3. Leverage laser screed technology. The combination of shrinkage-compensating concrete with 3D laser screed placement is particularly powerful for facilities with complex drainage requirements. The automated verification capabilities of laser screeds provide quality assurance that manual methods cannot match.
4. Engage experienced QC/QA teams. The collaboration between CTS Cement and IMI demonstrates the importance of experienced quality control teams in developing and monitoring the mix design. Type K cement behaves differently from ordinary portland cement, and proper testing protocols are essential.
5. Verify reinforcement requirements. The elimination of conventional temperature and shrinkage steel should be validated by a qualified slab consultant. While the Sugar Creek project demonstrated significant savings, each project’s loading, restraint conditions, and service environment must be individually assessed.

Construction Methods: Laser Screed Technology and Placement Techniques

Even the best concrete mix design requires proper placement and finishing to achieve its full potential. The Sugar Creek project leveraged advanced equipment and meticulous procedures to deliver the required floor performance.

Somero 3D Laser Screed for Drainage Precision

Managing 390 floor drains across a 330,000 square foot floor area with precise two-inch depressions at each drain location presented a formidable challenge. The Somero 3D laser screed proved essential to meeting these tolerances. The computerized system uses a 3D model of the finished floor to automatically adjust the screed head height as it moves across the slab, ensuring each section of concrete is placed at the correct elevation and slope.

An unexpected benefit of this technology emerged during placement: the computerized system identified a location where a floor drain had been inadvertently covered by concrete. Without this automated verification, the error might have gone unnoticed until after curing, requiring costly demolition and rework.

Finishing and Curing Procedures

The concrete finishing crew reported that the System-K mix showed no noticeable difference in workability compared to conventional concrete finishing. This was critical because specialized training or unfamiliar techniques could have introduced delays or quality issues on such a large project.

Each placement was followed by a seven-day wet curing process. Wet curing is essential for Type K cement because the expansive reaction requires adequate moisture to develop fully. Insufficient curing can prevent the cement from achieving its designed expansion, compromising the crack resistance of the finished slab. The seven-day period ensured maximum long-term performance and durability.

Upper Deck Placement Adaptations

An additional 1,000 cubic yards of System-K concrete was placed on the upper decks of the facility. For these elevated slabs, the mix design was modified with a high range water reducer. This adjustment allowed the concrete to be delivered with a six-inch slump while maintaining its shrinkage-compensating performance. The higher slump facilitated placement in the more constrained upper deck environment without requiring additional water that would have compromised strength and durability.

This adaptability of the Type K system demonstrates its suitability for projects with varied construction conditions. The same material science that eliminated control joints on the main floor also performed effectively in elevated slab applications with only minor mix adjustments. Accurate layout and measurement are critical for such precision work; Rtk and Ppk Surveying Technologies in Gps Surveying explores positioning technologies that support construction accuracy at this scale.

Performance Outcomes and Lessons for Future Projects

Floor construction began in October 2014 and was completed in April 2015. The results have validated the material selection and construction approach at every level.

The Sugar Creek food processing facility expansion stands as a compelling case study in the application of advanced concrete technology to solve real-world construction challenges. By addressing the fundamental material science of drying shrinkage, the project team delivered a floor system that meets the stringent demands of food processing while reducing construction complexity and long-term maintenance. As the construction industry continues to demand higher performance from concrete floor systems, Type K shrinkage-compensating concrete offers a proven solution that deserves broader consideration.

Food processing facilities demand exceptional floor performance. Hygiene regulations, drainage requirements, and heavy equipment loads impose stringent demands on concrete slabs that ordinary floor systems struggle to meet. The 330,000 square foot expansion of the Sugar Creek food processing facility in Cambridge City, Indiana demonstrates how advanced concrete technology can overcome these challenges. By adopting Type K shrinkage-compensating concrete, the project team eliminated the majority of contraction joints, prevented reflective cracking around extensive plumbing, and achieved a high performance floor that meets the exacting standards of modern food production. Understanding the material science and construction methods behind this success is valuable for any builder working on industrial or food-grade facilities. For broader context on industrial building performance, see Energy Saving Technologies Buildings for approaches that complement high performance floor systems.

Understanding the Demands of Food Processing Floor Systems

Food processing floors rank among the most demanding concrete applications in the construction industry. Unlike warehouse or light industrial slabs, these floors must satisfy multiple competing requirements simultaneously. They must withstand chemical attack from cleaning agents and food acids, resist bacterial growth, handle heavy point loads from processing equipment, and maintain precise drainage slopes over decades of service. The Sugar Creek expansion illustrates how these demands drove the selection of specialized concrete technology.

The Three Critical Challenges at Sugar Creek

The project team identified three major obstacles during the planning phase of this 330,000 square foot building expansion, which also included renovation of an existing adjacent 70,000 square foot meat and food processing facility.

1. Reflective cracking risk along plumbing lines. The Sous-Vide cooking process required complete removal and re-plumbing of the entire existing manufacturing floor. Water lines and drains running through the slab create restraint points where drying shrinkage stresses concentrate, producing reflective cracks that compromise hygiene and structural integrity.
2. Elimination of contraction joints for hygiene. Traditional contraction joints are harbors for bacterial growth. In a food processing environment, every joint represents a potential contamination point that requires ongoing maintenance and cleaning. The facility needed to eliminate the majority of these joints.
3. Precise sloping to 390 floor drains. The vast majority of the slab sloped to 390 floor drains depressed approximately two inches. Maintaining accurate slopes across such a large area required sophisticated placement and finishing techniques.

These challenges are not unique to food processing. Many industrial facilities face similar trade-offs between joint reduction, crack control, and drainage precision. The solution adopted at Sugar Creek has broad applicability across the construction industry. Projects using Innovative Technologies Revolutionizing Construction Industry demonstrate how advanced material science is reshaping conventional construction approaches.

Type K Shrinkage-Compensating Concrete: Material Science and Performance

The centerpiece of the Sugar Creek floor solution was CTS Cement’s System-K Shrinkage-Compensating Fiber Reinforced Concrete. This mix design uses Type K shrinkage-compensating cement, a specialized hydraulic cement that behaves fundamentally differently from ordinary portland cement in its response to drying shrinkage.

How Type K Cement Works

Ordinary portland cement concrete undergoes drying shrinkage as water evaporates from the hardened paste. This shrinkage creates tensile stresses within the concrete. When these stresses exceed the tensile strength of the concrete, cracking occurs. Control joints are typically installed to manage where these cracks form, but they introduce the hygiene and maintenance problems described above.

Type K cement solves this problem through controlled expansion. The cement contains an expansive component that, when hydrated, causes the concrete to expand slightly during the early curing period. This expansion is restrained by the reinforcement steel, piping, and other embedded elements within the slab. The restraint converts the expansion into compressive stress within the concrete. As the concrete subsequently undergoes drying shrinkage, it first must overcome this pre-existing compression before tensile stress can develop. The result is that the concrete remains in compression throughout its service life, effectively eliminating drying shrinkage cracking.

Mix Design and Quality Control

The CTS Cement and IMI QC/QA teams collaborated to produce a mix design that achieved extraordinary performance targets. The key specifications included:

The ability to pour slabs up to 150 feet by 150 feet without a single control joint represents a significant advancement over conventional concrete, where joint spacing is typically limited to 15 to 20 feet. This 75- to 100-fold increase in joint spacing transforms the feasibility of large-scale food processing and industrial floors.

Reinforcement Strategy: K-Fibers Replace Conventional Steel

Type K shrinkage-compensating cement was used in conjunction with reinforcing K-Fibers, which permitted the elimination of conventional secondary reinforcing steel throughout the slab design. The only steel required was two #4 bars at the perimeter of each pour and around columns or other penetrations. This approach delivered multiple benefits:

• Reduced material costs by eliminating temperature and shrinkage steel across the entire floor area
• Lower labor costs for reinforcement placement and tying
• Faster construction schedules without complex rebar detailing
• Elimination of potential corrosion pathways that conventional steel reinforcement introduces
• Improved fiber distribution throughout the concrete matrix for uniform crack resistance

The slab consultant, CRT Concrete Consulting, and the contractor, TWC Concrete Services, worked closely to validate this approach. Their confidence in the System-K design allowed them to move forward with a reinforcement strategy that would be impossible with conventional portland cement concrete. For projects where prefabricated elements complement cast-in-place solutions, Prefabrication Accelerating Facility Construction offers additional strategies for reducing on-site construction time.

Construction Methods: Laser Screed Technology and Placement Techniques

Even the best concrete mix design requires proper placement and finishing to achieve its full potential. The Sugar Creek project leveraged advanced equipment and meticulous procedures to deliver the required floor performance.

Somero 3D Laser Screed for Drainage Precision

Managing 390 floor drains across a 330,000 square foot floor area with precise two-inch depressions at each drain location presented a formidable challenge. The Somero 3D laser screed proved essential to meeting these tolerances. The computerized system uses a 3D model of the finished floor to automatically adjust the screed head height as it moves across the slab, ensuring each section of concrete is placed at the correct elevation and slope.

An unexpected benefit of this technology emerged during placement: the computerized system identified a location where a floor drain had been inadvertently covered by concrete. Without this automated verification, the error might have gone unnoticed until after curing, requiring costly demolition and rework.

Finishing and Curing Procedures

The concrete finishing crew reported that the System-K mix showed no noticeable difference in workability compared to conventional concrete finishing. This was critical because specialized training or unfamiliar techniques could have introduced delays or quality issues on such a large project.

Each placement was followed by a seven-day wet curing process. Wet curing is essential for Type K cement because the expansive reaction requires adequate moisture to develop fully. Insufficient curing can prevent the cement from achieving its designed expansion, compromising the crack resistance of the finished slab. The seven-day period ensured maximum long-term performance and durability.

Upper Deck Placement Adaptations

An additional 1,000 cubic yards of System-K concrete was placed on the upper decks of the facility. For these elevated slabs, the mix design was modified with a high range water reducer. This adjustment allowed the concrete to be delivered with a six-inch slump while maintaining its shrinkage-compensating performance. The higher slump facilitated placement in the more constrained upper deck environment without requiring additional water that would have compromised strength and durability.

This adaptability of the Type K system demonstrates its suitability for projects with varied construction conditions. The same material science that eliminated control joints on the main floor also performed effectively in elevated slab applications with only minor mix adjustments. Accurate layout and measurement are critical for such precision work; Rtk and Ppk Surveying Technologies in Gps Surveying explores positioning technologies that support construction accuracy at this scale.

Performance Outcomes and Lessons for Future Projects

Floor construction began in October 2014 and was completed in April 2015. The results have validated the material selection and construction approach at every level.

Measured Performance

• Zero cracking. The floor remains free of the cracking and curling commonly associated with conventional slab systems. This outcome directly reflects the Type K cement’s ability to maintain compressive stress in the concrete throughout its service life.
• Minimal construction and control joints. By eliminating the majority of joints, the facility substantially reduced bacterial harborage points, simplifying sanitation protocols and regulatory compliance.
• Successful drainage performance. All 390 floor drains function as designed, with proper sloping achieved through the laser screed guided placement.
• No curled slab edges. Edge curling, a common problem in large floor slabs, was prevented by the compressive stress state maintained by the Type K system.

Project Replication

The success of the Sugar Creek Cambridge City facility has had a direct impact on the owner’s subsequent projects. Sugar Creek has specified System-K concrete for other facilities, demonstrating that the approach is repeatable and scalable. This replication validates the investment in specialized mix design and quality control procedures.

Key Takeaways for Contractors and Specifiers

1. Evaluate shrinkage-compensating concrete early. For projects where joint reduction, crack control, or hygiene requirements are critical, Type K systems should be considered during the conceptual design phase rather than as a value engineering substitute.
2. Plan for adequate curing. Type K concrete requires a minimum seven-day wet curing period. Project schedules must accommodate this requirement, and contingency plans should address cold weather or low-humidity conditions that could affect curing.
3. Leverage laser screed technology. The combination of shrinkage-compensating concrete with 3D laser screed placement is particularly powerful for facilities with complex drainage requirements. The automated verification capabilities of laser screeds provide quality assurance that manual methods cannot match.
4. Engage experienced QC/QA teams. The collaboration between CTS Cement and IMI demonstrates the importance of experienced quality control teams in developing and monitoring the mix design. Type K cement behaves differently from ordinary portland cement, and proper testing protocols are essential.
5. Verify reinforcement requirements. The elimination of conventional temperature and shrinkage steel should be validated by a qualified slab consultant. While the Sugar Creek project demonstrated significant savings, each project’s loading, restraint conditions, and service environment must be individually assessed.

The Sugar Creek food processing facility expansion stands as a compelling case study in the application of advanced concrete technology to solve real-world construction challenges. By addressing the fundamental material science of drying shrinkage, the project team delivered a floor system that meets the stringent demands of food processing while reducing construction complexity and long-term maintenance. As the construction industry continues to demand higher performance from concrete floor systems, Type K shrinkage-compensating concrete offers a proven solution that deserves broader consideration.
