Apr 03, 2020 Cement production begins with limestone, a sedimentary rock. Once quarried, it is mixed with a silica source, such as industrial byproducts slag or fly ash, and gets fired in a kiln at 2,700 degrees Fahrenheit. What comes out of the kiln is called clinker. Cement plants grind clinker down to an extremely fine powder and mix in a few additives.
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.
