Prospects for the Development of Building Ceramics, Based on Stale Slags from the Non-Ferrous Metallurgy of Orenburg

The article deals with the problems of using wastes formed after extraction of copper, nickel, gold, etc. from slags. A review of existing developments in the field of using technogenic products for the production of ceramic building materials with desired properties was carried out. The results of the study of the prospects of using stale slags from non-ferrous metallurgy on the example of the slags from the Mednogorsk Copper-Sulfur Plant of the Orenburg region in combination with fusible clay from the Alimsaysky deposit for the production of ceramic brick are presented. The data of studying the technological properties of raw materials, the development of compositions are given. The effect of the material composition of the clay / slag mixture on the strength, shrinkage, water absorption and density of experimental samples – bricks after calcination in the range of 900– 1200 ° C is determined.

THE USE OF WASTE MINERAL WOOL IN THE PRODUCTION OF CERAMIC WALL MATERIALS

The environmental situation in Russia is characterized by a high level of anthropogenic impact on the environment, significant environmental consequences of past economic activity. Their disposal and storage costs 8-10 % of the cost of products, so the disposal of such waste is of paramount importance.Due to the involvement of multi-tonnage waste in the production of ceramic materials of mass consumption, which include wall materials, it is possible to radically change the parameters of the raw material base of Russia, which also helps to reduce environmental tensions in the regions. The reduction of reserves of traditional natural raw materials makes us look for new ways to replace it with different types of waste. The experience of advanced foreign countries has shown the technical feasibility of this area and the use of more as a tool to protect the environment from pollution. However, almost all basic building materials can be made from waste or from waste in combination with natural raw materials. On the basis of fusible clay and waste basalt-gabbro-norite charge, which is formed in the production of mineral wool obtained ceramic brick with high physical and mechanical properties, brick grade M150 and above. The absolute advantage of the use of multi-tonnage waste is the unloading of the environmental situation, which contributes to the solution of industrial waste disposal and environmental protection. Innovative proposals for the use of waste from the production of mineral wool in the production of wall materials - ceramic bricks based on fusible clay, the novelty of which is confirmed by patents of the Russian Federation.
