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.

Environmental security is currently one of the main components of the national security of the Russian Federation and includes not only control over the state of the environment, but also the implementation of measures to prevent the occurrence of environmental crises and disasters. The reduction of reserves of tradi-tional natural raw materials makes us look for new ways to replace it with different types of waste. The expe-rience 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. Due to the involvement of multi-tonnage waste in the production of ceramic materials of mass consumption, which include ceramic bricks, it is possi-ble to radically change the parameters of the raw material base of Russia, which also helps to reduce envi-ronmental tensions in the regions. Production of ceramic bricks  one of the most material-intensive sectors of the economy, so the rational use of fuel, raw materials and other material resources is a decisive factor in its successful development in the context of economic reform. In this regard, the use of waste in ceramic mate-rials is of particular relevance.

The article deals with the manufacture of modern structural ceramic materials from clay and loam deposits of the Republic of Sakha (Yakutia). The importance and relevance of the development of the production of building materials from local raw materials is emphasized, since this will certainly affect the effectiveness of the construction complex as a whole. The successful development of the construction complex is capable of not only stimulating growth in all sectors of the economy, but also contributes to solving the most pressing social problems. Today, Yakutia has huge reserves of mineral raw materials for the production of a wide range of building materials and products. Of practical interest are wall materials made from clay soils. Given the features of the region’s raw material base, this work focuses on additional processing of traditional material. Controlling the complex physicochemical and structural-mechanical transformations that occur during heat treatment, a methodology has been developed for creating a composite material that will allow competitive innovative materials with enhanced strength properties to be produced with a reinforcing element with a glassy phase matrix of mullite crystals. The fabricated samples have a wide range of physical and mechanical properties and allow using it as a high-quality structural building ceramics, as well as industrial floor technical tile.

Virgin raw materials can be partially replaced by glass waste in order to reduce the environmental impact being its recycling a significant problem for municipalities worldwide. In Italy in 2013, approximately 1,600,000 tons of container glass have been collected but it was not possible to recycle all of them in the glass melting process.This work is focused on the valorization of glass waste as raw material in new cement and ceramic products, to convert it from an environmental and economic burden to a profitable, added-value resource in the formulation of new mixes. Several parameters, such as grinding, forming, firing, etc. have been studied.It has been optimized the grinding and the reclaiming step of waste to obtain an alternative raw material for hot and cold consolidation processes. Chemical, physical and mechanical properties of products were carried out. The results show new real possibilities to use high amounts of glass waste as an alternative raw material in products consolidated either by hot or cold techniques, reducing the management problems of the glass waste.

Trends in housing development should be based on the geographical location and climatic conditions of the region, national characteristics and culture, natural resources, transport links, density and living standards. Construction significantly affects the socio-economic development of the region. In this regard, increasing the sustainability of the regional construction complex, which is based on the building materials industry and the construction industry is a relevant and promising area of research.Demand in the building materials market continues to stimulate increased interest in the development of new types of efficient and inexpensive building materials. Since construction is one of the most material-intensive sectors of the economy, which consumes a large number of construction materials and products, various measures are taken to reduce their cost.In this regard, recently in the construction seek to make greater use of local building materials. This allows you to unload transport from long-distance transportation and significantly reduces the cost of construction. However, the building materials industry cannot develop by focusing only on natural sources of raw materials, as the costs of their extraction and processing are constantly growing. The use of man-made waste provides production with a rich source of cheap and often already prepared raw materials, which reduces the cost of manufacturing building materials.One of the promising areas in the construction of affordable housing is the maximum use of building materials and products that can be obtained from local raw materials and industrial waste. As local building materials are offered: clay, sand, soil, straw, reeds, flax. The use of industrial waste solves both environmental, fuel and energy problems and expands the raw material base of building materials.

Introduction. This article discusses the possibility of expanding the colour palette of a ceramic shard. Due to the shortage of high-quality clay raw materials for the manufacture of plastic molded facing bricks, the problem of manufacturing ceramic wall materials by semi-dry pressing from low-quality clay rocks is urgent.Materials and methods. The main raw material was non-caking clay raw material with a low content of clay and a high content of silt particles. Some corrective additives were used to expand the colour palette of ceramic bricks. In the article, the authors used both standard methods for determining the physical and mechanical properties and modern methods for studying the phase composition of materials.Results. The possibility of enriching the colour range of a ceramic shard based on non-sintered clay raw materials has been experimentally confirmed, provided that the mixture contains flux additives. When receiving products with a clarified shard, light-colored flutes should be used.Conclusion. The possibility of enriching the colour range of a ceramic cap by adding white-burning clay, introducing bleaching and chromophore additives and technogenic products has been established. Due to the differences in the chemical composition of clay raw materials from individual deposits, an individual approach to each of them is required.

Abstract This paper reports the development and characterization of some new ceramic materials from hazardous bauxite red mud (50 to 100 wt.%) and blast furnace slag (10 and 50%). This research aimed to demonstrate the possibility of expanding the raw material base for ceramics production, completely replacing the traditional natural raw materials (clay and sand) by hazardous industrial wastes composites with increasing local and global sustainability. Studies on the physicochemical processes of the ceramic structure’s formation were conducted by the XRF, XRD, AAS, SEM with EDS, and LAMMA methods. Changes in flexural strength, linear shrinkage, water absorption, and density were determined during the sintering process at 1000°, 1050°, 1100°, 1150°, 1200°, and 1225°C. The ceramics` flexural strength after sintering at 1225°C reached 19.78 MPa due to the syntheses of the mainly glass-like structure formation, confirmed by SEM, EDS and isotopes LAMMA methods with the complete binding of the heavy metals.

Technogenic Raw Materials

Results of longstanding researches of Satbayev University scientists on the development of modified building materials to strengthen cracked mountain structures based on industrial waste are considered. Industrial processing of technogenic raw materials (enrichment and processing waste, overburden and enclosing rocks), which is similar in composition to natural and used in conventional trend, scarcely different from industrial processing of mineral raw materials. Creation of effective technologies for the processing of technogenic raw materials is an urgent task, which make it possible to obtain competitive products from it for various industries. Various methods of preparing solutions for strengthening of fractured rocks and building structures are analyzed. Research results of tailings of the Balkhash Mining and Metallurgical Combine and preparing solutions for strengthening fractured rocks and underground mining structures are presented. Rock mass strengthening in cracked areas is achieved by adding substances into the cracks, which after hardening and solidification with rocks, increase its shearing resistance characteristics. The most widespread hardening methods were cementation during mine workings (underground structures) in fractured rocks. Significance of obtained results for construction industry is in expansion and reproduction of raw material base of building materials industry through the use of Mining and metallurgical complex waste (tailings) and development of resource-saving technologies. Practical significance of work is in the detailed development of modified method for the production of building materials and products.
