THE COMPARISON OF BEARING CAPACITY AND STRESS-STRAIN BEHAVIOR OF COMPLEX LIGHTWEIGHT CONCRETE ELEMENTS, STRENGHTENED AND UNSUPPORTED BY COMPOSITE REINFORCEMENT

English abstract

The comparison of the results of bearing capacity and stress-strain behavior of complex lightweight concrete bending elements, strengthened and unsupported by composite reinforcement is provided in the article. The use of CFK Lamellen and SIKA CarboDur composite reinforcements to improve the bearing capacity and reduce the stress-strain behavior in lightweight concrete structures is little studied today. Such reinforcement is mostly used for strengthening and repairing of reinforced concrete constructions and structures [1-5]. Many countries of the world carry out experimental researches and widely apply non-metal reinforcement not only for strengthening structures but also in new construction. The main advantages of composite reinforcement are light weight, corrosion resistance, high strength, low thermal conductivity, environmentally friendly material, easiness in use, and so on. The comparison of the results of bearing capacity and stress-strain behavior of complex lightweight concrete bending elements strengthened and unsupported by composite reinforcement is presented in this article. As a result of experimental research, the following was discovered: strengthening of composite carbon reinforcement of complex lightweight concrete elements, 350 which were cut out from aerated concrete blocks and was deposited with slag concrete, changed the nature of the destruction of experimental samples. If the unsupported sample was broken in a brittle way, then such destruction was not observed in the strengthened one; - bearing capacity in reinforced samples B-1p and B-2p is higher in 1.2-2.2 times compared with the unsupported model B-1 and B-2, respectively; - deflections of strengthened samples are lower than in unsupported ones in 1.12-2.2 times at operating loading levels.
