INTRODUCTION Special cements differ from conventional Portland cements in their chemical and phase composition as well as in their properties. Their properties can be achieved by using a modified raw material mix, a grinding admixture or by adjusting the grinding fineness of the cement. Special cements include a number of cements whose production volumes are considerably lower compared to ...
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.
