Abstract:  Since last few years concrete technologists are putting in continuous efforts to minimize the consumption of cement in concrete. Cement offering architectural freedom and being second highest consumed material on earth is also the major cause for CO2 emission in atmosphere. With limited natural resources, durability issues and higher embodied energy, a need is felt to lessen or curtail the use of cement in concrete and replace the same with immensely available industrial by-products such as fly ash and GGBS. These materials, when activated by an alkaline solution exhibit similar strength and durability properties of that of conventional cement concrete. To understand the structural behaviour and crack development pattern, reinforced beams from Geopolymer concrete with fly ash and GGBS as source materials and that with OPC were cast and tested in laboratory. Two points loading was applied and observations were made till ultimate failure load. Also crack development patterns were studied. Similar tests were also done on the beams without reinforcement. From this study similarity in structural behaviour of beams with OPC and that of geopolymer concrete from fly ash and GGBS can be revealed and hence it can be a potential material for construction industry in future.
