Cement Wikipedia

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is behind only water as

Concrete With Limestone Calcined Clay Cement Concrete

Cement is normally made from Limestone, Silica, Alumina and Gypsum, but when all these ingredients are mixed at a temperature of 1500o C, it causes an emission of CO2 on environment. To reduce this, the researchers found that the use of clinker should be reduced. And here the answer is Limestone Calcined clay cement.
