Application of dispersed aluminosilicate waste in phosphate materials technology

The paper presents an aluminophosphate binder based on dispersed waste from fireclay production and orthophosphoric acid. The developed binder helped to obtain an adhesive composition with a shelf life of at least 1 year, as well as heat-resistant cellular concrete with an application temperature of 1500 °C and an average density of600...800 kg/m3. Heat-resistant phosphate cellular concrete was developed using aluminosilicate waste from fireclayproduction as an active additive in an amount of 10 % by weight of dry components. The paper demonstrates that the introduction of an additive into cellular concrete increases the strength characteristics while maintaining the average density at the same level in comparison with non-additive cellular concrete.
