Composition of cement. Introduction Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration.This is a complex process that is best understood by first understanding the chemical composition of cement.

Manufacturing of cement involves various raw materials and processes. Each process is explained chemical reactions for manufacture of Portland Cement. Cement is a greenish grey colored powder, made of calcined mixtures of clay and limestone. When mixed with water becomes a hard and strong building material.
