Home / calcined bauxite aggregate
Calcined bauxite aggregate possesses a series of good performances. For instance, the amount of high alumina is high while the amount of iron is low. What’s more, its hardness and refractory temperature is high while the coefficient of thermal expansion is low. In addition, the thermal properties of calcined bauxite aggregate is pretty stable.

Calcined bauxite is one of the principal ore of alu minum. Calcined bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85O℃ to 1600℃) .this removes moisture thereby increasing the alumina ...

The continuous use of load-bearing road surfaces often results in degradation over time, particularly if they are constructed from cement or aggregates that were poorly polished. Surfaces prepared from calcined bauxite exhibit good skid resistance properties, and this work describes a comparison of the wear resistance of six different kinds of calcined bauxite with the aim of identifying the ...
