Portland cement

Portland cement clinker is made by heating, in a cement kiln, a mixture of raw materials to a calcining temperature of above 600 °C (1,112 °F) and then a fusion temperature, which is about 1,450 °C (2,640 °F) for modern cements, to sinter the materials into clinker. The materials in cement clinker are alite, belite, tricalcium aluminate, and tetracalcium alumino ferrite. The aluminium, iron, and magnesium oxides are present as a fluxallowing the calcium silicates to form at a l

CEMENT RAW MATERIALS

Portland cement is the most widely produced cement, both in the UK and worldwide. The term ‘Portland cement’ was created by its inventor in 1824 because of the presumed resemblance of the set material to Portland Stone, the well-known natural building stone. Other varieties include rapid hardening, low heat, sulfate resisting, and low-alkali cements. In addition, blended cements are

How Cement Is Made Portland Cement Association

Portland cement is the basic ingredient of concrete. Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with
