PRODUCTION OF AN EFFECTIVE CERAMIC BRICK WITH USE OF TECHNOGENIC RAW MATERIALS
Keywords:bubbles, coal-wastes, ceramic bricks, porous structure
Unfortunately, today the most common way of dealing with industrial waste in Ukraine is to place them in dumps, waste heaps, sludge, tailing dumps, landfills and other storage facilities. They occupy millions of hectares of fertile land, is a source of air pollution, filtrate from them penetrates into soils, underground waters.
The aim of the work is to develop a resource-saving and environmentally-oriented technology of efficient ceramic materials with a high degree of utilization of man-made waste.
The prospect of the use of man-made raw materials in the manufacture of ceramics is shown. The main limiting factors on widespread use of wastes in ceramic technologies are given, as well as the well-known technological measures that make it possible to increase the volume of man-made waste utilization and use them as the main raw material in the manufacture of wall ceramics are given. It is established that among the various groups of man-made wastes for the production of ceramics are the waste of ferrous metallurgy, fuel and energy industry, with the note that the greatest suitability in terms of degree of preparedness, chemical and mineral composition is the waste of coal enrichment.
High indexes of frost resistance of experimental and industrial batch-based bricks based on waste, as well as bending strength, which are 12-60% higher than the normative indicators, are explained by the volume reinforcement of composite ceramic material. The estimation of technological efficiency of application of various methods of minimization of carbon in waste (special modes of roasting, introduction of clay additive in different amounts, preliminary thermal treatment) is estimated. It has been determined that the most expedient way to remove excess carbon from waste products is their preliminary heat treatment, which in addition activates the mineral part of waste and increases the rate of burning of residual carbon during subsequent firing of products.
