    Evaporation of volatiles Volatile phases in the cement kiln are principally alkali sulfates, with a much smaller proportion of alkali chlorides. As the partburned feed approaches the burning zone, these volatile phases are in liquid form and a proportion volatilizes, the remainder passing out of the kiln in the clinker as inclusions within the pores.

    Portland cement is a basic ingredient of concrete, mortar, and most nonspecialty grout. The most common use for Portland cement is to make concrete. Concrete is a composite material made of aggregate (gravel and sand), cement, and water. As a construction material, concrete can be cast in almost any shape, and once it hardens, can be a structural (load bearing) element.
