2steps of cement production process . cement is one of the most common and important building materials. it is a very critical ingredient because only cement has the ability to increase the viscosity of concrete which in turn provides the ability to..
Cement is the combination of calcium carbonate, silica, alumina and ferrous oxide, which are naturally found in limestone rock, chalk, shale andor clay. during the cement production process, these minerals are fused together by heating them to just under their melting point, forming a cement clinker between 3 to 20 mm in diameter.
