Cement Chemistry
This cement contains 32 – 45% Al 2 O 3, about 15% iron oxides, and 5% SiO 2, with the remainder composed of CaO. The primary phase present is Calcium Aluminate, or CA. This cement is produced by sintering a mixture of aluminous (typically bauxite) and calcareous components, and grinding to a fine powder.
