Analysis of the behavior of fiber-reinforced concrete reinforced with synthetic macrofiber under bending load

The article analyzes the test results of concrete and fiber-reinforced concrete specimens reinforced with Durus S500 synthetic macrofiber. The results of tests of the strength and energy characteristics of crack resistance of concrete and fiber-reinforced concrete specimens, carried out in accordance with the provisions of GOST 29167-2021, are considered. In addition, during the bending tests of concrete and fiber-reinforced concrete specimens, the distribution of specimen deformations along the height of the working section in the middle of the span was monitored. During the tests, equipment specially designed for such studies was used, including bending machines with the ability to record deformation diagrams and a sixteen-channel strain gauge station. The present study contributes to the accumulation of statistical and reference data on the behavior of fiber-reinforced concrete under load, which can be used in the design of fiber-reinforced concrete structures.
