Super Plasticizing Chemical Admixture Re dosing Procedure

Mineral Admixture - an overview

They concluded that GGBFS reduces the super plasticizer dosage in concrete because it acts as a super plasticizing agent replacement. Soutsos et al. (2005) found that the higher the cement replacement by GGBFS, and the lower the w/b ratio, the larger is the reduction in the super plasticizer dosage for high-strength concrete (HSC).
