OPC Cement | Types of OPC, 4 Manufacturing Steps - Civil Click

In the manufacture of OPC cement, heating is the main important step. In this step, with the help of conveyor belts, the product obtained from the mixing is passed into the Kiln. Firstly, to 550C the mix is preheated and all the moisture content is evaporated and clay is broken into silica, iron oxide, and aluminum oxide.

cement - History of cement | Britannica

History of cement. The origin of hydraulic cements goes back to ancient Greece and Rome.The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2,000 years ago and of subsequent construction work in western Europe.

Alternative Fuels in Cement Manufacturing - IntechOpen

Cement production involves the heating, calcining and sintering of blended and ground raw materials, typically limestone (CaCO 3) and other materials containing calcium, silicon oxides, aluminium and iron oxides to form clinker. Clinker production takes place at material temperatures of about 1450 °C in either rotary or shaft kilns.
