Understanding Limestone in Cement| Concrete .

26.03.2015 · 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 will likely improve the efficiency of water reducers.

Cement Production - an overview | ScienceDirect .

The cement production process, for example, starts with mining of limestone, which is then crushed and ground to powder. It is then preheated to save energy before being transferred to the kiln, the heart of the process. The kiln is then heated to a high temperature of up to 1480 degrees to convert the material to a molten form called clinker.
