BEARING STRENGTH AND DEFORMABILITY BENDED ELEMENTS FROM CLAYDITE-CONCRETE ON MULTICOMPONENT BINDER OF LONG-ACTION LOAD

Abstract

The results of experimental research of bended elements from claydite-concrete on multicomponent binder and quartz sand in case of long-action load are given. The scheme of experimental model-beams construction and reinforcement  is presented. The technique of experimental researches, results of bent elements tests and their analysis, and also volume, the purposes and results of tests are described. During the tests, the deflections of beams, the average deformation of the reinforcement and compressed and stretched zones concrete were measured. The conducted experimental researches made it possible to obtain data on the load-bearing capacity, deformability and crack formation of bending elements under long-action load, and to define the main parameters, which affect the deformation properties.  It was determined that level of long-acting load, the value of the reinforcement coefficient and the duration of exposure under load have a significant impact on the strength and deformation characteristics of the bent elements from claydite-concrete on multicomponent binder. It was proved that the calculation of the bearing capacity, crack resistance and deformability of the bending elements from claydite-concrete on multicomponent binder and quartz sand should be carried out according to the current regulations, using the specified values of the calculated parameters.
