Development of fiber-reinforced concrete with high flexural and compressive strength

Abstract

All buildings are exposed to flexural and compressive strength. To avoid the crack propagation, weakness of the concrete, and its brittle failure, engineers add reinforcements. The addition of fibers aims to reinforce the concrete. This study investigates several types of fibers (steel, Carbon, Glass, and Kevlar fiber) on mortar flexural and compressive strength. Sixteen mixes are tested with and without fibers on flexural and compression with two water-cement ratios (w/c=0.45 and w/c=0.5). Four types of fibers were used to reinforce 4x4x16cm mortar beams. This study shows that when it comes to performance, Kevlar fiber C% with steel fiber B% in the flexural test (w/c=0.5) rated first with 20% higher than PC and, rated second with 8% higher than PC in the flexural test (w/c=0.45). In the compression test (w/c=0.45 and w/c=0.5), Kevlar fiber C% with steel fiber B% mix rated in the first place with 31% and 39% higher than PC.
