| Title of the article | Economic feasibility of manufacturing hollow-core floor slabs from high-strength sand concrete |
| Abstract. | Studies were carried out to identify the economic feasibility of manufacturing hollow-core floor slabs with a height of 220 mm, having round voids with a diameter of 159 mm, non-tensioned reinforcement (series 1.141-1, issue 60) and prestressed reinforcement class A800 (series 1.141-1, issue 63), from high-strength sand concrete of classes VPB60 and VPB80 in comparison with slabs of heavy-weight concrete of classes B15 ... B80 in relation to the city of Kazan. The research is due to the absence of large aggregate deposits in a large part of the European territory of the Russian Federation or the presence of deposits of sedimentary rocks that are of limited use in reinforced concrete, with the widespread presence of sand, as well as the well-known economic efficiency of using high-strength concrete in the manufacture of loadbearing structures. The objectives of the research consisted in comparing the technical and economic indicators of slabs made of high-strength sand concrete of classes VPB60 and VPB80 with indicators of slabs made of heavy-weight concrete of classes B15 ... B80. The studies were carried out by the engineering method of calculation according to the current standards using the MS Excel PC. The strength and deformation characteristics of highstrength sand concrete were taken based on the results of studies of the Department of technology of building materials, products and structures (Kazan State University of Architecture and Engineering), obtained for concrete on the sands of local deposits. |
