Analysis of the Possibility of using Ash and Slag Waste from DPR Thermal Power Plants in Construction
Abstract: The analysis of the world experience in the disposal of ash and slag and construction waste is presented. Using the example of the Starobeshevskaya thermal power plant, the conditions for the formation of ash and slag waste, their mineral composition, qualitative and quantitative indicators and their impact on the environment are studied. It is shown that ash dumps occupy large territories, and their maintenance requires significant operating costs. A technological scheme for the extraction of microspheres and related components from fly ash has been developed, taking into account the provision of a closed circulating water supply system. The concept is substantiated and a multi-criteria model of joint processing of ash and slag and construction waste is proposed. The evaluation of the processing of microspheres and construction waste into secondary resources, with their subsequent use for building materials and pavement, was carried out. It is noted that the joint use of construction waste and waste management represents a combination of commercial and technical indicators – availability of resources, low cost, high strength and chemical resistance.
Keywords: microsphere, ash, waste, dumps, slag, ash-slag mixture.
