| Summary: | Relevance of the work is caused by the need to expend a source of raw materials of construction industry as well as to develop the effective technology of recycling wastes of drinking water treatment plant. The main aim of the research is to select a rational furnace charge composition based on loam and a deposit formed while treating drinking water to obtain structural ceramics. Research methods: differential and thermal analysis, X-ray phase analysis, mercury measurement of porosity, electronic microscopy. Results: The samples from masses with a deposit have lower apparent density and higher water absorption in comparison with the samples without additive that is caused by organic and mineral nature of a deposit. Addition of 10-15 % of deposit into furnace charge composition doesn't change and even promotes some increase in mechanical durability that is connected with the change in ceramics porosity structure. The further increase in quantity of deposit entered reduces mechanical characteristics of the burned samples in comparison with samples without additive. Conclusions: The deposit possesses a multifunctional resource for impacting agglomeration and formation of ceramics structure. The basis of applying the deposit in loam-based materials is physical and chemical affinity of their structure and properties based on their colloidal and chemical origin in nature. The rational maintenance of the additive in furnace charge amounts to 15 % on weight. The organic and mineral nature and energy potential of water purification deposit as well as a high degree of its technological readiness (doesn't demand a grinding) allow saving due to reduction of requirement for external thermal energy. |
