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.

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.

Plastic Properties

The possibility of obtaining wood and plant plastics without a binder (WP-WB) in the presence of a catalyst of man-ganese-containing sodium vanadomolybdophosphate has been investigated. The use of this catalyst makes it possible to reduce the temperature of hot pressing in closed molds from 1,800°C to 1,600°C. The fractional composition of the initial press raw material influences physical and mechanical properties of WP-WB. Higher values of the plastic properties are obtained by using a 0.7 mm fraction, which is associated with an increased specific surface area of the particles compared to 1.3 mm particles. The results has showed that the samples obtained by using the catalyst have increase in strength properties (flexural strength, flexural modulus, hardness) at lower pressing temperature, but reduction of water resistance performance has been observed . This is explained by the increase in the content of functional groups when using a catalyst. The process of obtaining plastic can be broken down into two successive stages: the first is hydrothermal destruction of lignin-carbohydrate complex (initial moisture of the press raw material is 12%, the temperature of hot pressing in closed molds is 160 ... .180 ° C) and partial chemical activation of lignin as a result of hydrogen peroxide and catalyst application; the second stage - formation of plastic with the formation of a network structure due to the formed functional groups. It is established that the values of physical and mechanical properties of WP-WB are higher than those of plastic obtained on the basis of plant raw materials (PP-WB). This can be explained by the fact that lignin of coniferous species has the guaiacylpropane structure, while plant raw material has a hydroxyphenylpropane structure
