Cement is often referred to as Portland cement, a generic term used for nearly all cement. It is the mixture from which many types of concrete are made and is called such due to its resemblance to a type of building stone quarried in the early part of the 19th century. This stone came from the Isle of Portland, located off the southern coast of England.

The History of Portland Cement. Cement as we know it was first developed by Joseph Aspdin, an enterprising 19thcentury British stonemason, who heated a mix of ground limestone and clay in his kitchen stove, then pulverized the concoction into a fine powder. The result was the world's first hydraulic cement: one that hardens when water is added.

Extraction and processing. Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.. The excavated materials are transported to the crushing ...
