Selected composition of structural heat-insulating ash tuff concrete class B15-20 on tuff rubble and ash using plasticizer D5, determined the calculated heat transfer resistance of the two-layer structure, the dependencies of the density and strength of the mixture from cement consumption for 1 m3.
The article describes the design of buildings for multi-apartment houses 139 series, designed for construction in the conditions of the Kabardino-Balkaria Republic (KBR). An analysis of existing wall panel variants based on their thermal characteristics was carried out and a new constructive solution was proposed using porous fillers of KBR. The coefficient of thermal conductivity of the proposed structural concrete is determined analytically and the heat engineering calculation of the external wall panel is presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
