Chemical Composition of Cement

modern cement is about 45 per cent and that of C2S is about 25 per cent. The calculated quantity of the compounds in cement varies greatly even for a relatively small change in the oxide composition of the raw materials. To manufacture a cement of stipulated compound composition, it becomes absolutely necessary to closely control the oxide
