Flexural behavior of reinforced geopolymer concrete beams

The present investigation embodies the flexural behavior of Geopolymer Concrete (GPC) beams cured under ambient temperature. Twelve reinforced concrete beams of size 175mm × 250 mm × 1500 mm were tested. The beams were tested under four point bending over an effective span of 1200mm. The percentage of tensile reinforcement and compressive strength of concrete were taken as the variables while maintaining the same cross section. The behavior was studied with reference to first crack load, service load and ultimate load. The results were found to be similar to that of conventional cement concrete reinforced beams.
