Title of the articleOn the question of studying the thermal conductivity of ceramic hollow-porous materials
Abstract.At the present stage of construction materials is urgent issue of effective hollow-porous ceramic materials. Using wall ceramic materials can improve the effective thermal properties of wall fences. The aim is to study the mechanisms of reduction of the average density of the ceramic shard with the introduction of the raw batch burnout agents of organic origin, such as buckwheat hulls, sawdust, and wood dust. With increasing amount of organic additives injected into the charge are reduced average density products and, hence improved thermal properties, but unfortunately reduces strength. Therefore, in order to improve the physical and mechanical characteristics of the ceramic crock should enter in the raw mixtures fluxing components. Introduction sub soap liquor helped to compensate for the loss of strength of the ceramic crock The thermal conductivity of ceramic products was calculated from the empirical relationships Nekrasov V.P., Kaufmann B.N., Vlasov O.B. thermal conductivity was calculated and plotted curves of the effect of the average density and the number of crock burnout agents in the form of buckwheat hulls, wood chips and wood dust on the thermal conductivity and total porosity ceramic crock. The result of the research is to obtain a ceramic brick with improved thermal characteristics.
Keywords.pottery, brick, sub soap lye, heat conductivity, average density.
