cement raw material composition

Natural Gray Concrete without Gray Cement

For economic and practical reasons, cement plants draw their raw materials from local sourc This means that the cement made at each plant starts with various blends of different raw materials As long as the end product meets industry standards for chemical composition and strength development, the color of the cement is considered unimportant.

RAW MATERIALS IN CEMENT PRODUCTION

The choice of composition of materials mixture with useful components generally is determined by plant’s geographical location and delivery of raw materials The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness.

Portland cement

Portland cement clinker is made by heating, in a cement kiln, a mixture of raw materials to a calcining temperature of above 600 °C (1,112 °F) and then a fusion temperature, which is about 1,450 °C (2,640 °F) for modern cements, to sinter the materials into clinker The materials in cement clinker are alite, belite, tri-calcium aluminate.
