Abstract

This study investigates the performance of reinforced concrete (RC) beams incorporating different proportions of fly ash (FA). A total of five beams, each with dimensions of 230 mm x 300 mm x 1600 mm, were constructed. Four beams were grade M20 (with a 28-day compressive strength of 20 MPa), with FA content varying at 0%, 5%, 20%, and 30%, while one beam was grade M25 with 20% FA. The M20 grade beam without FA served as the control beam (CB). After a 28-day curing period, the beams were tested using a three-point bending system, with parameters including central displacement, failure load, failure mode, and crack patterns. The performance of the beams was compared to that of the control beam. The findings indicated that the beam with 20% FA showed similar load-displacement behavior to the control beam, suggesting that 20% FA is the optimal proportion for enhanced performance.
