For many countries the problem of industrial and household waste disposal is particularly acute, since the annual accumulation of all types of waste is quite large (about 7 billion tons), and their reuse does not exceed 30 %. At the same time, industrial waste has a negative impact on living organisms and the environment. Therefore, ways of recycling household and production wastes are necessary. This article considers the problems of utilization, processing (recycling) of industrial and household waste and the prospects of their application in various industries. The influence of different formulations of initial components (microsilica, blast furnace slag, slaked lime), their fractions on physical and mechanical properties of the obtained new composite materials is considered. The obtained materials were investigated in order to determine the values of compressive strength and percentage of water absorption. Thus, all samples have low water absorption percentage (0 – 13.12 %), except for Sample 7 (41.34 %), consisting of 2 parts of microsilica, 1 part of slag and 1 part of lime. It was found that high values of compressive strength are observed in the samples which include microsilica. Samples 3 and 4, composed of microsilica and slag jointly, have the lowest compressive strength of 14.74 and 17.18 kgf/cm2, respectively. However, Sample 8, which is composed of 2 parts of microsilica, slag and lime simultaneously, is characterized by the highest compressive strength value of 51.16 kgf/cm2. Microsilica has a greater influence on the increase of strength properties. At the same time, the use of industrial waste in the creation of new secondary materials leads to a reduction in the cost of production, expansion of the raw material base of the country, as well as reducing the environmental load of the region.
