| Title of the article | Assessment of the influence of technological factors on the properties of building ceramics based on ash and slag mixtures at the thermal power plant of «Irkutskenergo» |
| Abstract. | The total accumulation of waste ash and slag mixtures today in the Russian Federation reaches about 1,5 billion tons. At the same time, only 1,5-2,1 million tons of annual emissions are recycled or used in various industries. It is obvious that in the coming years there will be a danger of large-scale environmental pollution, overfilling of ash and slag dumps, limiting the capacity of coal-fired generation and, probably, their removal from the energy balance. In this regard, the purpose of the work was to assess the effectiveness of ash and slag mixtures from thermal power plants for the production of building ceramics products. The objectives of the research include studying the properties of these mixtures and establishing the influence of technological factors on the strength of a raw ash ceramic sample during the drying process using the traditional production method of semi-dry pressing. Results. Using regression analysis, mathematical equations were obtained for the raw strength of samples based on ash and slag mixtures both before and after drying, depending on such technological factors as pressing pressure, molding humidity and specific surface area. The results of the main physical and mechanical parameters of ash ceramic samples after firing are presented: density, compressive strength and water absorption. Conclusions. The significance of the results obtained for the construction industry lies in the development of construction ceramic compositions based on such large-scale waste as ash and slag mixtures without changing the method of its production by semi-dry pressing. In terms of technological and physical-mechanical indicators, they meet modern regulatory documents and can be recommended for wide use in the production of ceramic products for construction purposes. |
