SRA 101 Shrinkage Reducing Admixture
1 Gallon / 3.8L
SRA-101 is a specialty liquid admixture specifically formulated to reduce drying shrinkage in concrete mix designs especially in rich GFRC mixes. Drying shrinkage of concrete is known to be associated with the surface tension of the mix water and the related capillarity they form when curing. SRA-101 typically reduces ultimate shrinkage values by up to 50% depending on the cement type used.
Typical dosages in standard mix designs are between 10-30oz / cwt of cement
