Abstract
Issues related to improving the quality of the operational properties of reinforced concrete and concrete structures by introducing discrete reinforcement - fiber reinforcement are topical tasks of building materials science. The aim of the study was to obtain high-tech concretes with increased flame retardant properties by introducing an optimal combination of fiber reinforcement components. The change in the compressive strength of concrete after fire tests, depending on the percentage of polypropylene fiber, is analyzed. The TSP-27-25 program, developed at the Tver State Technical University, which allows modeling various concrete compositions, was used in the calculation of the control compositions of fiber-reinforced concrete. It has been established that the addition of fiber makes it possible to increase the fire resistance of concrete with an optimal amount of it. An assessment of the strength characteristics of the studied samples after fire exposure is given. The influence of polypropylene fiber content on the nature of concrete destruction is investigated.
