Comparative Strength Analysis of Concrete with Nylon Fiber in Different Curing Media

Abstract

The compressive strength and splitting tensile strength of concrete reinforced with nylon fiber are examined in this work. Tests were done on concrete mixtures including different quantities of nylon fibers to see how they affected the mixtures compressive and splitting tensile strengths. The results show that adding nylon fibers to concrete usually improves its compressive strength and splitting tensile strength, with the highest performing concentrations. The use of nylon fiber-reinforced concrete (NFRC) has drawn interest as a possible way to improve both the durability and strength of regular concrete. The purpose of this study was to investigate how the performance of concrete is affected by the addition of nylon fiber. The addition of various percentages of nylon fibers to the concrete mix is 1%, 1.5%, 2% and 2.5% by volume. The mixtures were made with common ingredients for concrete, including water, fine and coarse aggregate, and cement. The greatest gains were mechanical qualities and durability was noted at 2.5% by volume, which was determined to be the ideal dosage of nylon fibers. The results of the study showed that the A5 mould with the highest proportion of nylon fiber (2.5%) used in water curing for 28 days had compressive strengths of about 36.62 MPa, 10.41 MPa in H2SO4 curing and 30.33 MPa in NaCl curing and splitting tensile strength 5.10 MPa in water curing, 1 MPa in H2SO4 curing and 4.96 MPa in NaCl curing.
