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 ...

Cement is made from gypsum, shale or clay, and limestone. The term "cement" is most often used to refer to Portland cement.
