SRA-157 is a liquid, shrinkage-reducing admixture, that can significantly decrease drying shrinkage in any Portland cement-based product. This is not expansive material, but rather functions by blocking capillaries of pore water, which is the major mechanism that causes drying shrinkage in concrete.
When added to concrete at a rate of 2 % by weight of cementitious can reduce shrinkage (ASTM C 157) by up to 80% at 28 days of age and by up to 50% at one year of age.
Features and Benefits
High level of shrinkage reduction that can eliminate cracking due to drying shrinkage in restrained concrete
Reduces potential for cracking
Improves aesthetics
Increases water tightness of the mix
Improves durability of the concrete
Reduces creep and curling of slabs
Decreases carbonation at the surface of slabs
Riteks VMA-42
Riteks VMA 42 is a viscosity modifying admixture designed to enable the production of self-compacting concrete. When added to the mix, concrete treated with Riteks VMA 42 is more stable and resistant to segregation.
Features and Benefits
Increases the viscosity and cohesiveness of the concrete mix
Reduces concrete bleed water
Reduces segregation in high water cementitious and high slump mixes
Aids in concrete mix stability with gap-graded aggregates
Can be introduced at the batch plant or jobsite
Enables the production of self compacting concrete
Normal setting characteristics throughout the dosage range
Enhances the appearance of finished surfaces
Easy to disperse
Applications
Lean concrete mixes with minimum cementitious contents
Mixes requiring reduction or elimination of bleed water
Highly fluid self-consolidating concrete mixes that require the use of viscosity. Aids in concrete mix stability with gap-graded aggregates modifier to eliminate segregation
Mixes requiring reduction or elimination of bleed water. Enables the production of self compacting concrete

Slump Retain 240
Riteks Slump Retain 240 is a revolutionary new technology based on significant advances in the admixture industry. When used as part of an admixture system, it provides slump retention without retardation. Slump Retain 240 gives the concrete producer the ability to immediately create the ideal admixture system for fluctuating regional raw materials, environmental conditions and project requirements.
