Recycling
Ash and slag waste (ASW) is a finely dispersed mineral material resulting from the combustion of brown and hard coal at thermal power plants. The involvement of ash and slag waste in industrial circulation is one of the effective ways to solve the issue of energy and resource saving. Utilization of ash and slag waste in industrial production will provide a solution to the environmental problem of environmental pollution by industrial waste - technogenic fine dust and harmful effluents by gradually reducing the rate of increasing the area of ash dumps with their subsequent complete elimination.
In this work, the influence of ash and slag waste on the physical and mechanical characteristics of building mixtures was studied. Gypsum samples were made with the addition of aluminosilicate concentrate and compared with native ones. The strength indicators for the studied samples were determined, according to which the introduction of an aluminosilicate concentrate into the building composition increases the fracture strength by 10%. The method of differential scanning calorimetry was used to study thermal effects in the samples in order to establish phase changes. To assess the internal structure of building mixtures, the specific surface area and pore size distribution were determined by the method of low-temperature nitrogen adsorption.
