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

The role of CEMENT in the 2050 LOW CARBON

2018-9-28  The main raw material used in cement production has traditionally been limestone. Limestone is abundantly available, but over 60% of the industry’s CO 2 emissions are caused by transformation of limestone into lime. Limestone needed to make clinker can be partially substituted by a range of alternative calcium
