Abstract: Cement substitutes and concrete alternatives are currently on the market to help in creating concrete a very ecofriendly material. In cement concrete production, heating and compounding method need large amounts of energy and emits minacious amounts of CO2 into the atmosphere. There has been an increasing significant interest in the development of cement less concrete called geopolymer concrete. In this study, cement is replaced entirely by ash and GGBS for making of geopolymer concrete. Now a days, the scarcity of river sand can have an effect on the development trade and hence there’s a requirement of finding a replacement different material to switch the river sand. Non-reactive recycled waste glass is chosen as alternative to the river sand. Various grades of concrete including M 20, M 40 and M 60 grades are developed in GP concrete and also same proportion is used for making GP concrete with glass aggregate. In geopolymer preparation, NaOH of 8 molarity concentration is used. Flexural behaviour of beams is studied by casting of nine beams of size 125 mm × 200 mm × 1100 mm. The beams are designed as under reinforced sections. Out of nine beams, three beams of M 20, M 40 and M 60 grade conventional cement concrete beams, three beams of GP beams and the remaining three beams are made with RWGFA in GP. Beams are tested under two point loading for flexure. The ultimate load carrying capability of all beams is obtained. The crack and deflections of the beams are studied. The experimental results are compared with finite element modeling using ANSYS software.
