11.6 portland cement manufacturing 11.6.1 process description17 portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. more than 30 raw materials are known to be used in the manufacture of portland cement, and these.

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 c in a cement kiln. in this process, the chemical bonds of the raw materials are broken down and then they are.
