Alkali-activated slag binders from rock-wool production wastes
The article exposes the results of studies on the production of alkali-activated slag binders from rock-wool production wastes and their composite derivatives, which are resistant to corrosive effects of biological environment. Thermal analysis showed that the structurization in the "rock wool production waste-water-NaOH" system is most efficient with the NaOH/waste ratio of 0.02–0.03, and the main newlyformed phases in the solidified alkali-activated slag composites are low-basic calcium hydrosilicates and analcime. The best values of the physical and mechanical properties of obtained binders are achieved with a waste grinding fineness of 400–450 m2/kg. The compressive strength of the developed composite materials reaches 68 MPa and bending strength is 13.5 MPa with a waste grinding fineness of 300 m2/kg. Composites based on binders made of rock-wool production waste are waterproof and funginert, and individual compounds are fungicidal.
