Understanding Limestone in Cement| Concrete Construction

Mar 26, 2015· The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser cement gradation
