The substantiation of the need to develop and implement new resource-saving technologies for the production of construction mixtures using aggregates obtained as a result of complex processing of solid inorganic construction waste is provided. Analytical studies of technogenic waste processing technologies for obtaining building materials have been conducted. The results of the study of the experience of construction scrap processing are presented, with confirmation of the expediency of the fact that the technology of recycling accumulated construction scrap dumps in the territory where the destroyed buildings were located does not require any new specialized measures. The projected volumes of building materials in the composition of residential construction objects with various quantitative parameters of the constituent components of the elements of the fencing structures are presented. Analytical studies have established that the accumulated volumes of construction scrap from the destruction of elements of buildings and structures in the vast majority include the remains of concrete, reinforced concrete, expanded clay concrete, brickwork made of ceramic and silicate products. Experimental series of aggregate samples were made using experimental samples of construction scrap, their granulometric characteristics were determined and physical parameters were investigated. With the use of regulatory and technical literature, the predicted prescription parameters of the concrete mixture using a new variety of aggregates obtained by re-processing of construction scrap were compiled. The presence of reactive substances on the surface of the obtained aggregates was substantiated and the presence of increased physical and mechanical characteristics of the samples with a decrease in the binder content was confirmed. Recipe and technological parameters for the production of wall building materials using the obtained multicomponent building mixtures are proposed. The results of tests of physical and mechanical characteristics of test samples of concrete using aggregates from solid inorganic waste are presented.
