Portland cement clinker is made by heating a homogeneous mixture of raw materials in a rotary kiln at high temperature . The products of the chemical reaction aggregate together at their sintering temperature, about 1,450 °C (2,640 °F).
Portland cement is a product obtained by the calcination at a very high temperature, an intimate mixture of correctly proportioned calcareous and argillaceous materials. The calcined product which is called clinker. Clinker is then finally pulverized by grinding into a very fine powder and is finally mixed with calcium sulphate or gypsum to obtain cement.
