Abstract In this article, work was carried out to study the chemical, mineralogical composition and toxicological properties of waste (phosphogypsum, phosphorus slags, overburden) of the phosphorus industry, the optimal content of the grain composition of gravel-sand mixtures in the composition of road mixtures (crushed stone, sand-gravel, sand) and structures of the Zhambyl region of the Republic of Kazakhstan. The possibilities of using slag-mineral mixtures in the year - round construction of highways were studied on the basis of a comprehensive study of the physicochemical processes of hardening and the formation of the structure of slag-mineral materials at negative temperatures. Technological regimes for the construction of roads of various technical categories from slag binding materials, reformed after long-term freezing, have been established. New, unparalleled, binding road mixtures have been created to increase the utilization of waste from the phosphorus industry and expand the raw material base of road building materials. The main directions of application of road mixtures based on industrial waste for the purposes of road construction have been developed: construction of structural layers of road pavements; construction of road bed layers.

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.

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.

Cellular Concrete

The use of local natural and technogenic raw materialsallows expansion of the raw material base for producing the building materials and reduction of production cost. Creation of low energy-intensive technologies for producing the building materials is a priority for the construction industry. The chemical and mineralogical composition of industrial wastes makes it possible to use them for producing the low-clinker or clinker-free composite binders. Secondary resources can be used as an active mineral additive that would allow to reduce the cement consumption. The properties of cellular concrete depend on the formed cement matrix structure, the strength of the inter-pore partitions. Quality can be managed by directional formation of the mechanical framework. Providing the necessary granulometric composition of the cellular concrete components is decisive for the mechanical framework formation. The inter-pore partition structure in the cellular concrete is a developed silicate matrix formed by hydration products and a siliceous component. Therefore, when designing this structure, an analogy with ordinary dense concrete is quite possible. The basic principle for designing the concrete composition consists in creating a dense packaging of the constituent components.

It is shown that at present the current system of environmental regulation in Russia is divorced from the real context in which to exist. One of the most promising areas for the use of waste production is ─ involving them recycled as secondary material or energy resources. On the basis of waste oil shale obtained heat-insulating materials with high physical-mechanical indicators. Due to the involvement of industrial waste in manufacturing of heat-insulating materials may dramatically change the parameters of the raw material base of Russia, which also contributes to reducing environmental impact in the regions. The use of waste fuel and energy complex: inter-shale clay and slate slag in the production of insulating materials contributes to recycling of industrial waste, the protection of the environment and expansion of raw materials base for production of ceramic building materials. The compositions of the developed compositions, proposed to obtain a lightweight brick and a porous filler, the authors of this article obtained three patents of the Russian Federation. Utilization of industrial wastes contributes to the development of "green" economy.

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.
