Slag Cement Association

Concrete mixes with slag cement tend to have a smoother and more workable consistency than when working with only portland cement. Slag cement enhances the consolidation and pumping of concrete by improving its rheology, or flowable nature. This leads to an easier-to-work-with paste and a smoother concrete
