“…The geometric parameters of the beams were assigned based on the analysis of literature sources [4,5,6,8,9,10,11] 60x120mm, where the larger size is the height of the section, the total length of the element is 1.4 m. Based on the analysis of work [11], the deflectometer is set only in the middle of the span.…”

“…The beams were tested for pure bending -the most characteristic type of loading for such elements [9,10,11,12,13,14,15,16], this test scheme also corresponds to the papers devoted to the study of the "work" of rubcon beams under load [4,5,6].…”

“…It was established experimentally that the strength of fibrorubcon corresponds to the class of highstrength concrete, but the modulus of elasticity of rubcon corresponds to the modulus of elasticity of traditional concrete, which can be seen from Table 3. It should be noted that the modulus of elasticity affects the deformability of building elements made of this polymer concrete, which can also be seen in [4,5,6]. The prerequisites for studying fibrorubcon bending structures are presented in [5].…”

The study of the deformability of building structures, especially bending elements, is an integral part ofa full study of structures, because it is often the deformability determines the size of the cross section ofthe element, to ensure the necessary rigidity of building structures. For beam elements, the mostimportant during exploitation are vertical displacement – deflections.For application (especially under the influence of aggressive environment) as a material of productionof the building structures we offer rubber concrete-polymer concrete which has favorable deformationand strength characteristics, high adhesion to metal surfaces. It is important to note that the compositionof fibrorubcon used industrial waste such as fly ash and fibers steel cord. It was establishedexperimentally that the strength of fibrorubcon corresponds to the class of high-strength concrete, butthe modulus of elasticity of rubcon corresponds to the modulus of elasticity of traditional concrete. Tostudy the deformability of rubcon and fibrorubcon bending elements we have made a beam with alongitudinal reinforcement percentage μ = 0...8.4%.The beams were tested for pure bending – the most characteristic type of loading for such elements. Onthe basis of the tests, a limit on the percentage of longitudinal reinforcement to satisfaction therequirements of the current standards for maximum deflections of fibrorubcon and rubcon beams wasset.

“…The above indicates the prospect of studying the effect of fiber reinforcement on the strength characteristics of polymer concrete, since this method of reinforcement can increase the tensile strength of the material, as well as increase the rigidity of the structure as a whole. The prerequisites for studying fiber rubcon bending structures are presented in [6,7].…”

In order to research on the influence of the height of the fiber reinforcement zone on the normal sections crack resistance, we produced and tested rubcon beams of rectangular cross section with mixed reinforcement; our studies showed that the height of the fiber reinforcement zone has a similar effect on the normal sections crack resistance with the percentage of longitudinal reinforcement. It is important to note that the arrangement of fiber reinforcement at 3/4 of the section height greatly complicates the process of manufacturing the beam while not increasing the strength of the tensile zone compared to the beams with the location of the fiber over the entire height of the section.
