WebManufacture of cement. Portland cement is manufactured by crushing, milling and proportioning the following materials: Lime or calcium oxide, CaO: from limestone, chalk, shells, shale or calcareous rock. Silica, SiO 2: from sand, old bottles, clay or argillaceous rock. Alumina, Al 2 O 3: from bauxite, recycled aluminum, clay. Carbon disulfide (also spelled as carbon disulphide) is an inorganic compound with the chemical formula CS2 and structure S=C=S. It is a colorless liquid, which is used as a building block in organic synthesis. It has a pleasant, ether- or chloroform-like odor, but commercial samples are usually yellowish and are typically contaminated with foul-smelling impurities.
