Bottom Ash Waste Used in Different Construction Materials

The paper presents the investigations of the composition and properties of the bottom ash waste generated by Seversk thermal power plant of the Tomsk region. The compositions suggested for construction materials (fired and hydrothermal) are based on the bottom ash waste. Mechanical-and-physical and physicochemical properties of the produced specimens are investigated in this paper. Phase compositions are determined for fired materials based on the bottom ash waste, and a possibility of producing ash-based mineral wool is defined herein. The produced ash-containing fiber possesses a higher chemical resistance and performance characteristics due to its higher acidity index.
