The Indian mining industry plays an important role in supplying the raw materials used in cement industry. The most important raw material used in the cement manufacturing process is the Limestone that is found in the sedimentary rock. Limestone rocks are changed by dynamic metamorphism to turn into marbles.Cement clinker is manufactured by heating the blended and ground raw material typically limestone and clay or shale and other materials to partial fusion. The clinker burning takes place at a temperature of 1450 C in kilns, which are normally inclined rotating cylinders lined with heat-resistant bricks.

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.

    Producers know that replacing some of the clinker in portland cement with ground limestone offers benefits, the most important being that it reduces the embodied CO2 of the cement. Modifying a concrete mix design to replace higher carbon materials with lower carbon ingredients is an effective strategy to reduce its environmental footprint.Producers know that replacing some of the clinker in portland cement with ground limestone offers benefits, the most important being that it reduces the embodied CO2 of the cement. Modifying a concrete mix design to replace higher carbon materials with lower carbon ingredients is an effective strategy to reduce its environmental footprint.Mar 01, 2020 It has been reported that limestone filler alone is not able to prevent segregation or bleeding, and that there is no difference between cement pastes mixed with limestone filler and pure OPC pastes in terms of rheology . On the other hand, if one needs low slump and low spread, the use of metakaolin is recommended because this material creates a strong interconnected network in the paste, increasing the yield stress and viscosity of the cement paste.
