As CO2 emissions are increasing in the atmosphere and causes global warming with the production of cement, the alternative pozzolanic material is needed. The alternative pozzolanic material for cement in the production of concrete is GGBS. Geopolymer Concrete (GPC) is an alternative material for conventional concrete. Geopolymer concrete is made by mixing GGBS, fine aggregate, coarse aggregate, and alkaline activator solution. GGBS is a by-product of the iron industry. This paper shows the results on experimental investigation done on reinforced geopolymer concrete beams to know the flexural behavior. The alkaline activator solution is prepared by sodium hydroxide NaOH and sodium silicate Na2SiO3 in 1:2.5 ratio. The flexural behavior of the beams is examined with different molars of NaOH solution. The GPC beams are compared with conventional reinforced concrete beam of M35 grade concrete. The type of curing adopted in the experimental study is ambient. The size of beam is 750 mm × 150 mm × 150 mm. The flexural test is done on the loading frame of capacity 250 tons. The ultimate load, cracking load and the maximum deflection and the crack pattern is determined, and the load Vs deflection graphs are plotted. This experimental study gives a clear conclusion on the flexural behavior of conventional reinforced concrete beam and reinforced geopolymer concrete beam made with GGBS
