| Title of the article | Recycling of inter-shale clay and slag from ferrotitanium smelting into clinker brick production |
| Abstract. | Problem statement. Considering the depletion of reserves and the shortage of natural traditional aluminosilicate conditioned raw materials for the manufacture of high-burning (more than 1200oC) ceramic materials, it is necessary to find and investigate production waste instead of traditional raw materials. Advanced Western countries have shown this experience, and they also used it as a tool to protect the environment from various negative consequences. The aim of the work is to obtain clinker bricks with improved physical and mechanical properties. The objectives of the research are to study the possibility of using technogenic raw materials, the development of compositions for the production of clinker bricks, and to study the effect of slag from the smelting of ferrotitanium on the physical and mechanical properties of clinker bricks based on intershale clay. Results. The article shows that it is possible to obtain a clinker brick based on intershale clay without the use of aluminum-containing (A12O3 >70%) slag from ferrotitanium smelting. The introduction of slag from ferrotitanium smelting into the compositions of ceramic masses contributes to the production of clinker bricks with high physical and mechanical properties. Conclusions. The significance of the results obtained for the construction industry and for the environment is that the use of man-made raw materials (industrial waste) makes it possible to obtain clinker bricks without the use of traditional natural raw materials, expands the raw material base for the production of building materials and promotes waste disposal. |
