Finely-dispersed Wastes of Titanium Production as an Additive for Manufacturing of Building Materials

The possibility of using titanium sludge, which is a finely-dispersed waste with high content of titanium dioxide TiO 2 and calcium fluoride CaF 2 in the construction industry as an agent replacing cement binder and improving the properties of concrete composition, is considered. The properties of modified concretes with different percentage of binder replacement were studied, the characteristics of strength, porosity and water absorption were determined according to standardized methods, and the composition showing the best characteristics was revealed. The mechanism of the effect of the main waste compounds on concrete is described.
