One of the most important problems of humanity nowadays is environmental pollution, which affects human health and life. There are nearly 50 million tons of emissions (ashslag wastes) realized in the environment per year, which indicates a physical contamination of nature and deterioration of the ecological situation on Earth. The processing and further use of emissions is a solution that can significantly reduce negative impact from industrial activity on the environment. The use of ash and slag emissions occupies one of the leading positions in this case. Recycled waste can considerably reduce the use of natural raw materials in construction industry. Ash-slag wastes, in contrast to natural ash, are not depleted, but on the contrary, their number increases every year, which in turn creates the prospects for their study and use. Replacement of material components with secondary waste will help to solve the problem of processing emissions, reduce the consumption of natural resources and contribute to introduction of new construction materials based on ash and slag waste. The appearance of such product can solve the problem of shortage of building materials in some regions of Russia (Altai and Primorsky territory). The paper is concerned with the results of complex processing of ash-slag wastes, description of products received by adding the components of such wastes, spheres of application, analysis of obtained characteristics, and comparison of the new product with the concrete without components based on waste.
