Portland cement is a product that is made by mixing, grinding and kilning raw materials of limestone, marl, clay, iron ore, pyrite ash, bauxite, etc., and grinding the resulting clinker with a certain amount of regulator (usually gypsum); which cures and gains strength after a certain period of time after mixing with the water.
It is generally used in high strength structures, cold weather concrete works, prefabricated buildings, tunnel-mold applications, the production of building chemicals and in the application of foundation concretes.
