Abstract

The issues of industrial waste disposal are one of the priorities of the environmental policy of the regional authorities, in the territory of which enterprises produce fabricated raw materials. In addition, the reduction in the reserves of traditional raw materials makes us look for new ways to replace it with various types of waste. The construction materials industry, unlike other industries, has unlimited possibilities of using waste, which is explained by the large scale of the construction complex, its materiality and the range of different products. In the present work investigated the possibilities for using the tonnage of waste: waste of energy ─ slag material and nanotehnologija carbonate sludge in the production of ceramic bricks based on rare ─ beidellite clay. The resulting ceramic bricks had high physical and mechanical properties. For the production of bricks as a binder and burning additives used ash-slag material Togliatti TPP. The presence of fine carbonate sludge in the raw material makes it less sensitive to drying, i.e. reduces the cracking of bricks. The presence of nanoscale particles in the system increases the volume of adsorption and chemisorption bound water and reduces the volume of capillary-bound and free water, which leads to an increase in the plasticity of the ceramic mass and a reduction in the clay binder in the compositions of ceramic masses. Developed innovative proposals for the use of multi-tonnage waste in the production of ceramic bricks, the novelty of which is confirmed by a patent of the Russian Federation.
