Calculated amount of lime is added in the manufacturing of Portland cement, If it is excess in amount, it reduces strength of cement, because it makes the cement to expand and disintegrate. (II) SILICA: Lime undergoes reaction with silica to form dicalcium silicate (C2S). These play important role in development of strength to cement.
The image depicts two diagrams labeled "Cement Production" and "Concrete Production". The first diagram illustrates the process of cement production starting with limestone(80%) and clay(20%) entering a crusher, becoming powder, passing through a rotating heater with heat application before being grinded into cement and packed into bags.
The diagram illustrates the way in which cement is made and how it is then used in process of making the concrete. Overall, the limestone and clay pass through fivestages before being bagged and ready for uses as a cement which then accounts for 15% of the four materials used for produce the concrete.

Limestone (calcite, CaCO3) is an abundant and cost-effective source of calcium oxide (CaO) for cement and lime production. However, the thermochemical decomposition of limestone (∼800 °C, 1 bar) to produce lime (CaO) results in substantial carbon dioxide (CO2(g)) emissions and energy use, i.e., ∼1 tonne [t] of CO2 and ∼1.4 MWh per t of CaO produced. …
