Raw materials for cement manufacturing

alumina and iron in the finished product, known as cement clinker. Cement is therefore essentially a mixture of calcium silicates and smaller amounts of calcium aluminates that react with water and cause the cement to set. The requirement for calcium is met by using high calcium limestone (or its equivalent calcareous raw material) and clay, mudstone or shale as the source of most of the silica and alumina. Portland cement clinker is nodules (diameters, 525 mm) of sintered material produced by heating a homogeneous mixture of raw materials in a kiln to a sintering temperature of approximately 1450 C for modern cements. The resulting clinker consists of four main minerals 11 1.

Jun 24, 2021 Limestone may be the main ingredient of cement production, but minor constituents can play a major role in clinker and cement quality. Source Shutterstock. The primary raw material for clinker development is typically calcareous combined with a second supply comprising clay as an alumino-silicate origin. An impure calcareous comprising clay and silicon dioxide (SiO2) is usually used. The amount of this calcium carbonate (CaCO3) can be as small as 80 percent.
