Cement Industry Overview

The manufacturing process of Portland cement uses magnesia as a raw material in dry process plants. An excess amount of magnesia may make the cement unsound and expansive, but a little amount of it can add strength to the cement. Production of MgO-based cement also causes less CO2 emission. All cement is limited to a content of 6% MgO.

For understanding cement composition, one must know the functionality of Cement ingredients. By altering the amount of an ingredient during cement production, one can achieve the desired cement quality. Ingredients of Cement Composition of Cement. There are eight major ingredients of cement. The following image is showing the ingredients of cement:

Cement - Extraction and processing | Britannica

The production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity. Cement production accounts for about 5% of total anthropogenic emissions (IFC, 2017). Cement-based structures constitute the largest surface area of all man-made structures (Odigure, 2009).
