How Cement Is Made

Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement.

The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg. Weight of coarse aggregate = 3 x 364.5 = 1093.5 kg. Concrete Calculator: Calculate Quantities of Materials for Concrete

Cement - Wikipedia

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. There are two main forms of cement: Geopolymer cement and Portland Cement.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.
