Portland cement clinker - Overview

Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties.

This page gives a thumbnail sketch. For more information see the following pages, or better still, the Understanding Cement book - links at the bottom of this page.

Portland cement clinker contains four principal minerals:

Alite: approximately tricalcium silicate (typically about 65% of the total)
Belite: approximately dicalcium silicate (typically about 15% of the total)
Aluminate: very approximately tricalcium aluminate (typically about 7% of the total)
Ferrite: very approximately tetracalcium aluminoferrite (typically about 8% of the total)
The balance is made up of alkali sulfates and minor impurities. The typical mineral contents shown are subject to wide variation.
