HydroMax® Internal Curing SAP Admixture provides an internal source of water necessary to replace that consumed by chemical shrinkage during hydration. As the cement hydrates, this water is drawn from the pores in the admixture’s water reservoirs and absorbed into the pores of the cement paste. This process assists traditional curing techniques and can minimize the development of autogenous shrinkage, help in avoiding early-age cracking, and improve strength.
