Cemex Cement is based in the United States and lists Ordinary Portland Cement, Cement 52,5N/R, White Portland Cement and Blended Cement on Global Trade Plaza. The Ordinary Portland Cement is described as a fine powder produced by calcining limestone, clay and iron ore at 1,450 °C, then grinding the resulting clinker with gypsum and other chemical additives. The company also offers blended cements with lower clinker content through the addition of supplementary cementitious materials. White Portland Cement is manufactured using limestone, low iron content kaolin clay and gypsum, and is used in architectural works requiring brightness, mosaics, artificial granite, sculptural casts and other applications where white prevails. Blended hydraulic cements are produced by intergrinding or blending Portland cement with supplementary cementitious materials such as ground granulated blast furnace slag, fly ash, silica fume, calcined clay, hydrated lime and other pozzolans.
