What is Cement

What is Cement:

Cement is made by grinding together a mixture of limestone and clay, which is then heated at a temperature of 1,450°C. As a result granular substance is obtained and  called “clinker,” a combination of calcium, silicate, alumina and iron oxide. After that clinker and a certain amount of limestone, gypsum and other raw materials are ground together and what results as a fine mineral powder called ‘cement’.
