Chemical Composition of Cement

Tricalcium silicate and dicalcium silicate are the most important compounds responsible for strength. Together they constitute 70 to 80 per cent of cement. The average C3S content in 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

Silicate - Wikipedia

In chemistry, a silicate is any member of a family of anions consisting of silicon and oxygen, usually with the general formula [SiO− 4−x] n, where 0 ≤ x < 2. The family includes orthosilicate SiO4− 4, metasilicate SiO2− 3, and pyrosilicate Si 2O6− 7. The name is also used for any salt of such anions, such as sodium metasilicate; or any ester containing the corresponding chemical group, such as tetramethyl .
