The cement sector can offer both industrially mature and industrially promising uses for bauxite residue, BR. Even if the cement sector is not panacea and most probably case specific conditions will eventually determine a multitude of valorisation paths per refinery, it does offer a tangible paradigm.
Low cement castable is the castable whose cao content less than 3, usually the refractory cement dosage is from 3-8, but high grade cement is needed to ensure the strength of the castable. comparing to common refractory castable, low cement castable has better performance in high temperature, and require less water, it makes the castable has lower porosity and higher density.
Calcined bauxite manufacturers produce calcined bauxite by firing heating the superior grade bauxite at high temperature from 850 to 1600. this removes moisture thereby increasing the alumina content. compared to an alumina content of about 57 to 58 in raw bauxite, calcined bauxite has an alumina content of 75 to 90 .
Some typical materials used for calcium carbonate in cement manufacturing are limestone, chalks, marbles, marls, and oyster shell. some typical materials used for alumina in the cement manufacturing are shale, clay, slags, fly ash, bauxite, alumina process waste, and granite.
Bauxite cement also named aluminate cement is kind of cerement made from limestone and bauxite. the main ingredient of bauxite cement is calcium aluminate. scope of the report china is the largest consumption country of bauxite cement in the world in the past few years and it will keep the same position in the next few years.
Cement, one of the most important building materials, is a binding agent that sets and hardens to adhere to building units such as stones, bricks, tiles, etc. cement generally refers to a very fine powdery substance chiefly made up of limestone calcium, sand or clay silicon, bauxite aluminum and iron ore, and may include shells, chalk, marl, shale, clay, blast furnace slag, slate.
