About Cement :

Ordinary Portland cement is predominantly compounds of calcium silicate and calcium aluminates with a small proportion of gypsum. It is produced by burring or sintering, at a temperature in excess of 1400°C, a finely ground mixture of raw materials which contain predominantly calcium carbonate, aluminum oxide, silica and iron oxide. The cooled clinker formed is ground under controlled conditions with the addition of typically 5% gypsum.
