This paper presents the results of the experimental investigations carried out to determine and to compare the flexural behavior of geopolymer concrete (GPC) beams with conventional concrete beams of same grade. A total of twenty beams consisting of twelve GPC beam specimens and eight PCC beam specimens were considered in this study. The beams were designed as under reinforced with tensile reinforcement ratios 0.55%, 0.83%, 1.02% and 1.3%. The beams were tested under two point monotonic loading. Performance aspects such as load carrying capacity, first crack load, ultimate load, loaddeflection behavior, moment-curvature behavior, crack width, crack spacing and the modes of failure of both types of beams were studied. The test results showed that the geopolymer concrete exhibits better performance compared to conventional concrete of same grade
