| Title of the article | The production of ash-based building ceramics based on ash-and-slag waste from thermal power plants of the Irkutsk region is an example of the best available technology for their disposal |
| Abstract. | Problem statement. The aim of the work is to assess the possibility and efficiency of using ash and slag waste from the Irkutsk region on the example of ash and slag waste from the dump of the Novo-Ziminskaya CHP in the technology of producing ash ceramics. Results. The chemical composition of the ash by X-ray diffraction analysis was determined. Using the method of mathematical planning, the optimal technological indicators and the main physical and mechanical characteristics of ash ceramics (density, water absorption, complete shrinkage and compressive strength) were established. The kinetics of changes in the strength of molded specimens was studied depending on several factors: compacting pressure, percentage of flux, the content of superplasticizer used to improve the forming ability of the charge and reduce the water content. The results of the work are presented in the form of a regression equation and tables that clearly reflect the relationship between strength and the above factors. Conclusions. The significance of the results obtained for the construction industry lies in the development of ash ceramics compositions that meet the requirements of the current regulatory documentation. Good technical performance has been achieved, including its appearance and surface quality, which will allow the use of ash ceramics for the production of facing products. The optimum of technological parameters (compacting pressure, flux and superplasticizer content) and their effect on compressive strength have been determined. |
