Nowadays a development of industry and technology reached levels, that allow to consider industrial wastes as valuable raw material for construction materials’ production. The factor, which prevents from using many kinds of wastes, is a negative impact that they have on environment and people. However, technologies allowing a usage of a simultaneous utilization of wastes with a mutual neutralization effect are known from a practice. The aim of the presented research is the analysis of previous studies on the topic of a utilization of industrial wastes in construction materials and a development of methodological approaches to their simultaneous utilization with an obtainment of construction materials which can be competitive in comparison with analogues produced from natural raw materials. In the paper, methodological approaches to a utilization of heterogeneous industrial waste products and a production of construction materials with a low negative impact on environment are presented. The basis of methodological approaches comprises principles used in the best obtainable technologies. Developed theoretical basis passed approbation during the creation of the technology of a simultaneous utilization of blast furnace slags and waste products of soda production in construction materials manufacture. In case of a utilization of blast furnace slags in construction materials production there is an increased migration of heavy metals and water-soluble compounds. With an introduction of soda m wastes, which have an increased alkaline reserve, to construction materials’ composition, water soluble compounds convert in marginally soluble and insoluble. The achieved result is a 2.5-3 times decreased migration of heavy metals in environment in case of contact with water both in acid and alkaline media.
