Key Advantages

Reduction of Plastic Phase Shrinkage

SRA-K60 effectively controls shrinkage during the plastic stage of the mix, ensuring better workability and minimizing early-age cracks.
Minimization of Post-Drying Shrinkage

It continuously works to reduce shrinkage after the drying phase, helping to maintain the structural integrity and longevity of the material.
Minimal Impact on Strength

The formulation is designed to enhance shrinkage control without adversely affecting the overall strength of the hardened product.
Reduction of Capillary Tension

By lowering capillary forces within the mortar or concrete, SRA-K60 improves the material’s compactness and durability.
