Ordinary Portland cement results from the calcination of limestone and silica in the following reaction. Limestone + silica (1450oC) = Portland cement + carbon dioxide 5CaCO 3 + 2SiO 2 (3CaO, SiO 2) (2CaO, SiO 2) + 5CO 2 The production of 1 tonne of cement produces tonnes of chemical CO 2, in a reaction that takes place at 1450oC. An
Portland cement can be made by following two different processes – a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.
