20191221Cement as a binding material is a very important building material. Almost every construction work requires cement. Therefore the composition of cement is a matter of great interest to engineers. For understanding cement composition one must know the functionality of Cement
Read on to know more about how to make cement. Limestone sand and clay are the three main raw materials required to make cement. They contain the four essential mineral elements required in making cement i.e. calcium silicon aluminum and iron. horiontal crushing mills are also used in this process. Calcination.

2000317This is a fluxing agent which reduces the melting temperature of the raw materials in the kiln from 3000 o F to 2600 o F. It hydrates rapidly but does not contribute much to strength of the cement paste. By mixing these compounds appropriately manufacturers can produce different types of cement to suit several construction environments.
