Abstract—The present experimental program is conducted to study the structural behavior of reinforced Geopolymer concrete beams under two points loading. Geoploymer concrete mixtures are prepared by varying the percentage of fly ash content and experimental study carried on strength parameters, the best suited mixtures based on the optimal strength of compression and flexure was selected for manufacture of beam. Investigation is confined to find Moment of resistance of the beam and compared with the conventional concrete beam analysis as per IS 456-2000 code of practice. Deflections, stiffness and crack patterns are also studied in the investigations. Experimental investigations of moment of resistance of the beams are validated over the analysis results. The defalcation, stiffness and crack patterns are found similar to conventional concrete beam.
