CEMENT RAW MATERIALS - British Geological Survey


Portland cement is the most widely produced cement, both in the UK and worldwide. The term 'Portland cement' was created by its inventor in 1824 because of the presumed resemblance of the set material to Portland Stone, the well-known natural building stone. Other varieties include rapid hardening, low heat, sulfate resisting, and low-alkali cements. In addition, blended cements are ...
