Study on the Behavior of Reinforced Concrete Beams with Basalt Fiber

Abstract

This study focuses on the behavior and performance of reinforced concrete beams incorporating basalt fibers, aiming to evaluate the effectiveness of basalt fiber reinforcement in enhancing bending capacity and delaying the cracking of concrete beams. The test specimens were divided into two groups: reinforced concrete beams without basalt fibers and reinforced concrete beams with basalt fibers added at ratios of 10, 20, and 30 kilograms per cubic meter. The experimental results indicated that the inclusion of basalt fibers significantly improved the bending capacity and effectively delayed the occurrence of cracks, particularly during the initial loading stages before beam failure. The use of basalt fibers is thus considered an efficient method for strengthening and extending the service life of reinforced concrete beams.
