High Alumina Cement refers to an inorganic material that develops a condensed texture if it is connected with water. This construction materials contains an outstanding refractory, rapid curing property and resistance to chemical reactions. High Alumina Cement is formed by grinding clinkers which are developed with calcining bauxite and lime. The bauxite refers to a raw material of aluminium ...
· The main materials used in cement production are minerals containing calcium oxide, silex, alumina and iron oxide. These components are rarely found in one type of raw material; therefore, for the cement production the raw mix is selected for the following components:
Calcium aluminate cements are cements consisting predominantly of hydraulic calcium aluminates. Alternative names are "aluminous cement", "highalumina cement" and "Ciment fondu" in French. They are used in a number of smallscale, specialized appliions.
· The high purity indices and fineness of alumina dust makes it possible to consider it a valuable technogenic raw material, suitable for producing a broad range of refractory and ceramic materials: highalumina chamotte, fuzed and sintered corundum, spinels, mullite, codierite, anorthite, etc. This product is of considerable practical interest as a high quality raw material for producing ...
Cement is a manufactured product made by blending different raw materials and firing them at a high temperature in order to achieve precise chemical proportions of lime, silica, alumina and iron in the finished product, known as cement clinker. Cement is therefore essentially a mixture of calcium silies and smaller amounts of calcium aluminates that react with water and cause the cement to ...
