28· More than half of CO2 emissions in the cement industry are released during the process of making clinker, the manmade rock needed to produce cement. Clinker is ground in a mill with gypsum to produce portland cement. Blending limestone in the Cement clinker Wikipedia,The Portland clinker essentially consists of four minerals: two calcium silicates, alite (Ca3Si) and belite (Ca2Si), along with tricalcium aluminate (Ca3Al) and calcium aluminoferrite (Ca4AlFe) (Ca3Si), Ca2Si, Ca3Al, Ca4AlFe are abbreviations reflecting the stoichiometry of key elements). These main mineral phases are produced by heating at high temperature clays and limestone. The major raw material for the clinkermaking is usually limestone mixed with a second material cont

PLC THE USE OF LIMESTONE POWDER AS AN ALTERNATIVE ,strength of cement (42.5 MPa) as per EN 1971 standard requirements. Furthermore, it was found that 2535% limestone addition by weight results in specifically intergrinding of clinker and limestone. It is an established fact that 0.9 ton of CO 2 is emitted per ton of cement [11]. However,
