What is the formula of cement?
Unfortunately, there is no easy answer to this question, as there are many different types of cement that vary in the compounds they consist of. 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 Hope this gets you started. Good luck.
