Understanding Limestone in Cement| Concrete …
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. In …

Role of lime stone in cement? - Page 1 of 2
Limestone is no more considered an inert material. World wide studies have shown that limestone takes part in hydration reaction and early strength development in cement. On the addition of limestone powder to cement, a reaction between CaCO 3 of limestone and aluminate phase of cement (C 3 A) takes place, which is quite similar to gypsum-C 3 A reaction.

A metered proportion of crushed, dried limestone is fed to the finish grinding mill, along with clinker and gypsum. In almost all cases, the limestone used in PLC is the same limestone used as a raw material for cementmaking at that plant. This makes sense not only because the supply is relatively unlimited and low in cost, but because most cement plants use a limestone raw material that is more conducive …
