Ordinary Portland Cement (OPC)

Cement is basically a complex mixture of Calcium Silicates. Hence, Cement production requires a source of calcium and a source of calcium.

The source of Calcium is the Lime stone which constitutes 70-85 % of the raw material mix .Source of Silica is Mineral Clay or Sand or Shale (8-20%). Also Bauxite ore (2 to 4.5%) and Iron Oxide (0.5 - 6%) are added to improve certain properties .Also, Gypsum (3% - 5%) is added at the grinding stage To sum up, the raw materials are Lime Stone : 70 - 85 %,Silica : 8 - 20 %, Bauxite : 2 - 4 %,Iron Oxide : 0.5 - 6 %,Gypsum : 3 - 5 %.

Joseph Aspadin of Leeds, England invented Portland Cement. In 1824, he manufactured cement, in a rudimentary form, by burning mixture of limestone and clay. After that, this cement is named as OPC with Lime stone as main ingredient. Limestone is a sedimentary rock, mainly composed of mineral calcite. It is a very useful mineral found naturally. The primary source of the Limestone is usually marine biology/marine organisms, which settle out of the water column and are deposited on the ocean floors .Chemically, Limestone is called Calcium Carbonate ( CaCO3). Generally, It is mined from the captive quarries of the cement plant.

This cement is generally applied to constructions, blocks, pipes, tiles, decorative and Asbestos. During construction of any structure, it is used for Concreting
