Additives for cement - CHRYSO

Reduction of cement agglomeration eliminates the coating on grinding media and the reagglomeration of cement particles after grinding CHRYSO® Activators modify the surface charges' density on the cement particles, therefore offsetting the Van Der Waals forces. As a consequence, the cement particles reagglomeration is significantly
