What is Portland Cement? Portland cement is a generic term used to describe any type of hydraulic cement that is produced by heating a mixture of limestone and clay or limestone and shale in a kiln to a high temperature of 1,450 °C. Then the resulting clinker is ground to a fine powder which is known as Portland Cement.

Portland cement is a versatile bonding agent composed of clinker compounds and calcium sulfate. The most common type of Portland cement, called ordinary Portland cement (OPC), is gray in color and widely used in the production of concrete, mortar, stucco, and non-specialty grout. It comes in five types, each with …
The primary raw materials for the mass production of cement can either be calcareous or argillaceous. The former ingredient is obtained from limestone, marl, cement rock, chalk, etc., whereas the latter one is procured from clay, slate, blast furnace slag, shale, etc. The process of manufacturing cement can either be a wet process or a dry process.
