In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (012 in) to 25 millimetres (098 in) in diameter, produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

Raw materials for cement manufacture Materials used in the Cement Industry in Britain and Ireland Almost any mineral can be used in a cement rawmix, provided that the bulk composition of the mixture will produce the desired calcium silicates and fluxes (see clinker), and provided that certain deleterious components are minimizedBroadly speaking, minerals containing high levels of calcium.

The main raw material used in cement production has traditionally been limestone Limestone is abundantly available, but over 60% of the industry’s CO 2 emissions are caused by transformation of limestone into lime, called “decarbonation” Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone substitution.

Bangladesh: The Bangladesh Cement Manufacturers Association (BCMA) says a new import tax on raw materials and a distribution levy will increase the price of cement and place a burden on the construction industry The new duties will add 8% to the existing 15% of value-added tax (VAT) already liable on raw materials, according to the Daily Sun newspaper.

Use of raw materials in the cement industry vdz Geologically speaking, about 90 per cent of the quarried limestone dates back to the mesozoic (Cretaceous, Jurassic, Triassic) and is thus between 65 and 250 million years old In 2015, the German cement industry procured around 41 million tonnes of primary raw materials.
