MANUFACTURING Of PORTLAND CEMENT Portland cement is made by heating raw materials rich in oxides of silicon, calcium, aluminum and iron to temperatures of around 1200 - 1400o C. The chemical reactions that occur within the partially molten mass result from the formation of the four main cement materials. Tricalcium silicate (CaO)3•SiO2 C3S 45-75% Dicalcium silicate (CaO)2•SiO2 C2S 7-32% ...
