Influence of different types of fibers on flexural tensile strength

Abstract

The paper presents the influence of the application of different types of fibers in concrete beams on the flexural tensile strength. All concrete beams were made of the same component materials and composition, except for the amount of fiber, which is varied. After hardening, the height of the concrete beams in the central part was reduced to 125 mm by cutting. The measurement of flexural tensile strength by was performed according to SRPS EN 14651. Based on the test results, depending on the type, shape, quantity and distribution of fibers, the values of ultimate and residual strengths were analyzed.
