Ordinary Portland Cement is predominantly compounds of calcium silicate and calcium aluminate with small proportion of gypsum. It's produced by buring or sintering at a temperature in excess of 1400ˇăC, finely ground mixture of raw materials which contain predominantly calcium carbonate, aluminium oxide, silica and iron oxide. Cooled clinker formed is ground under controlled conditions with the addition of typically 5% gypsum.
