Riteks CSE-4 offers a higher Pozzolonic Activity Index (PAI) for improved compressive strength development for light weight slurries. Riteks CSE-4 reacts with free lime produced during hydration of cement and produces additional cementitious material for improved compressive development. Riteks CSE-4 also provides benefits such as extender properties & free water control, all at much reduced loadings than other pozzolans.
