Performance Engineered Concrete Mixtures

Engineering Concrete Excellence: A Legacy of Innovation
Developing and validating concrete mixtures to meet specific performance requirements.
- High-performance
- Non-shrink
(K-cement and shrinkage-compensating additives) - Heavyweight
(180-300 pcf) - Roller-compacted
- Self-consolidating
- Rapid hardening and ultra-rapid hardening
- Cellular low density
(25-65 pcf) - Pervious
- Underwater
- Architectural
(discoloration, resistant; simulating natural enviornment; sculptural), and others

Our laboratories are equipped to evaluate properties of fresh concrete affecting constructability, such as the formability of low-slump pavement mixtures intended for slip-forming, segregation resistance of self-consolidating concrete, bleeding, setting time, and others. We qualify concrete for compressive, flexural, direct and splitting tensile strengths, Poisson ratio and modulus of elasticity, creep, shrinkage, coefficient of thermal expansion, cracking resistance, rapid chloride permeability, coefficient of chloride diffusion (ASTM & EN), bulk resistivity, adiabatic temperature rise, and other physical properties. Our laboratories are equipped for simulating the production, consolidation, and curing of cast-in-place and precast concrete. We use various types of mixers (drum mixers, pan mixers, high-speed shear mixers), external and internal vircators, steam curing chambers, temperature-control and temperature-matching curing chambers, foam generators for cellular concrete, and other specialized equipment.
