What s d chemical composition of lime and cement?
which lime? limestone is CaCO3, Quick lime is CaO and slaked lime is Ca(OH)2 chemical composition of cement? this is a stupid question. Cement is a mixture of not precisely known composition, as different compositions are required for different applications. But, as an example, here's a breakdown of the chemical formulas used in portland cement. It consists of five compounds as listed below. 50% - Tricalcium silicate - Ca3SiO5 or 3CaO.SiO2 25% - Dicalcium silicate - Ca2SiO4 or 2CaO.SiO2 10% - Tricalcium aluminate - Ca3Al2O6 or 3CaO .Al2O3 10% - Tetracalcium aluminoferrite - Ca4Al2Fe2O10 or 4CaO.Al2O3.Fe2O3 5% - Gypsum - CaSO4.2H2O
