Types of cement

Three broad classifications of cement are on sale in the UK:

CEM I – made from ground cement clinker and a small percentage of gypsum to control the material’s setting time when mixed with water.

CEM II – is a cement containing between 6 and 35%, fly ash, limestone or blastfurnace slag, a by-product of steel production.

CEM III – is a cement containing between 36 and 95% blastfurnace slag.

There are a variety of cement products designed for specific end-uses. For further information on these, visit the MPA Cement's members websites.
