This research work aims to study the sustainability of Geopolymer concrete beam with partial replacement of fly ash by waste Granite Powder. Reinforced Geopolymer concrete beam of M35 grade with 15% replacement of granite powder is compared with conventional reinforced geopolymer concrete beam. Beam of cross section 150 x 150mm and length 700mm were casted and cured under ambient conditions. The tension reinforcement consists of two bars of 12 mm diameter and compression reinforcement consists of two bars of 6 mm diameter. The shear reinforcement was made with 8mm stirrups at 90 cm spacing along the length. The beams thus casted is tested under two point static loading to study its flexural behaviour. The studies demonstrated that the performance of 15% replaced Geopolymer Concrete Beam is better than the conventional Geopolymer concrete beam. The addition of waste granite powder increase the Ultimate load carrying capacity and ensures superior ductile behaviour. This investigation work encourages the use of waste granite powder in the geopolymer concrete thereby enhancing its structural behaviour.
