The cement industry is a major contributor to global carbon emissions. The production of limestone is a major source of carbon emissions, accounting for 55–70% of the entire production process. Therefore, seeking alternative to replace raw materials is an effective way to reduce carbon emission in cement industry.
average clinker-to-cement ratio over all cement types in the EU27 is 73.7%1. The use of other constituents in cement and the reduction of the clinker-to-cement ratio means lower emissions and lower energy use. Clinker can be blended with a range of alternative materials, including pozzolans, finely ground limestone

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 flue gases produced from cement industry contain CO 2 formed during clinker production, which is the main component of cement, and CO 2 formed from fuel combustion (average total 17.8%).
This limestone is naturally packed with a substance called calcium carbonate, which is similar to cement. When regular cement is mixed with water to make concrete, a chemical reaction helps everything stick together and harden. But when limestone is added to the mix, it reacts with the cement and creates even more of this sticking-together matter.
