Cement Materials used in Manufacturing of Cement CachedLime. It is the main constituent used in cement manufacturing. It is responsible for imparting the cementing property to cement. An excess quantity of lime causes expansion and disintegration of the cement. Silica. This plays a major role in imparting strength to concrete. Silica undergoes a chemical reaction with calcium to form dicalcium silicate (C2S) and tricalcium silicates (C3S). Alumina. This forms complex compounds with silica and calcium to improve the setting capacity of the cement. It acts as a flux and lowers the clinkering temperature. Iron Oxide. This is mainly responsible for imparting colour to cement. The hardness and strength of the cement are also improved to a certain extent. It helps in the fusion of materials during the cement manufacturing process. See all full list on gharpedia.com
