Chemcrete SRA is a liquid admixture designed to reduce drying shrinkage, and in doing so, reduce the resulting cracking.
Chemcrete SRA acts by reducing the surface tension of the water in the pores and therefore reduces the internal forces in the concrete. Generally, this leads to a 50% reduction in both plastic shrinkage and drying shrinkage initially and at 28 days with a 30% reduction at one year and later.
Dosage: 1.0 – 2.5% by weight of cement
