| Popis: | Develop recommendations for the use of polymer-concrete bending structures is impossible without the creation or optimization of existing methods of calculation, this is especially true for bending elements that use multi-level reinforcement. Для применения (especially under the influence of aggressive environment) for use as a material for the manufacture of bending structures, we offer rubber concrete. – polymer-concrete, which is characterized by high strength characteristics. It is important to note that the composition of fibrorubcon used industrial waste such as fly ash and steel cord. Beams made from cauton and fibrocahuton were tested for pure bending - the most characteristic form of loading in the study of such elements. As a result of the theoretical studies of polymer concrete beams, the prerequisites were established for the calculation of the first group of limit states of rubcon beams and the method for calculating fibrorubcon beams was optimized. It was determined that fiber reinforcement with a percentage of reinforcement by mass of the rubcon element equal to 2.5% corresponds to the work of rod longitudinal reinforcement with a value of μ = 0.34%. |
