Portland Cement: Properties, Composition, Types and Uses

Ans: It is a hydraulic cement which was patented in 1824 by Joseph Aspidin. It is produced by heating a mixture of limestone and clay in a kiln to a high temperature of 1,450 °C. Then the clinker is ground to a fine powder which is known as Portland Cement. It has a wide range of applications in construction work.
