Use of raw materials in the cement industry

Short routes for supply of raw materials take pressure off of traffic volumes and reduce transport-related emission of pollutants. Procurement of natural raw materials will continue to form the basis for cement manufacture in future. Use of alternative raw materials can be further increased to a certain extent.

Raw materials Understanding Cement

Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.

How Cement Is Made

The labs also analyze and test the finished product to ensure that it complies with all industry specifications. The most common way to manufacture portland cement is through a dry method. The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed.
