Portlant cement Portland cement was first produced commercially in 19th century in england. Portland cement is currently defined as a mixture of argillaceous (i.e. clay-like) and calcaneous (i.e. containing CaCO3 or other insoluble calcium salts) materials mixed with gypsum (CaSO4⋅2H2O) sintered and then pulverised into a fine powder.
