To the Issue of Energy Efficiency of Building Materials Production in the Republic of Kazakhstan (on the example of production technology for wall ceramics and expanded clay)
It is shown that the issues of energy saving and energy efficiency in the Republic of Kazakhstan has become a priority for sustainable development of every modern enterprise focused on producing competitive products along with quality assurance and affordable cost. The materials of the scientific analysis of the results of scientific research conducted by a group of scientists of the Korkyt Ata Kyzylorda State University to ensure the energy efficiency of the technology of production of wall ceramics and expanded clay are presented. Results of the work on a comprehensive study of oil sludge and the possibility of using them in the composition of ceramic masses as an energy-releasing and modifying component for the production of high-quality ceramic bricks and expanded clay are given. It is established that the process of oil sludge burning in the composition of organic-mineral conglomerate mixture increases the temperature inside the furnace and accelerates the sintering process of the ceramic shard. At the same time, the firing time of the product is reduced. Together, these processes at the stage of firing the product provide a reduction of energy costs. On the basis of comprehensive research works conducted by the group of scientists, it is concluded that the oil sludge should be considered not as a waste, but as a valuable energy-releasing and additional modifying raw material for the production of high quality wall ceramics and expanded clay affordable for consumers.
