Alternative raw material Lafarge - Cement,

Cement manufacturing generates large amounts of CO2 during a physical-chemical process called "decarbonation". In this process, limestone is heated to very high temperatures to produce clinker, which then is ground down to produce cement. However, the amount of clinker required can be reduced by substituting alternatives called cement admixtures.

How Cement Is Made - Portland Cement

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.

Cement: Materials and manufacturing process

Cement Works No 2 by Eric Revilious 1934. The essential components of cement • Chemically, cement is a mixture of calcium silicates and small amounts of calcium aluminates that react with water and cause the cement to set. • Calcium derives from limestone and clay, mudstone or shale as the source of the silica and alumina.

Cement Manufacturing Process - Civil

Cement is a hydraulic binder, i.e. it hardens when water is added to cement powder. Joseph Aspdin, a Leeds Builder and bricklayer had invented the Portland cement in 1824. In this process,Aspdin mixed and ground hard limestone and finely divided clay into the form of slurry and calcined it in a furnace similar to a lime kiln ,till carbon di oxide was expelled.
