In the process of production of concrete, the emission of carbon dioxide has become a life-threatening issue and a major drawback towards sustainable development, as there is need to reduce and control this carbon dioxide. It is therefore essential to find a substitute greener material to the existing OPC concrete. Since its significant minor carbon footprint and with usage of industrial by-products, which includes fly ash and ground granulated blast-furnace slag in geopolymer concrete is recognized as a sustainable substitutes. Fly ash is well-off in silicate and alumina, hence it reacts with alkaline solution to generate alumina silicate gel that binds the aggregate to manufacture a good quality concrete. Literature on the flexural behavior of geopolymer concrete (GPC) beams have been studied and compared with the reference concrete beams of the respective grade. From the literature, It has been observed that the development of flexural cracks are relatively less in geopolymer RCC beams compared to conventional beams, the failure occurred in the beams was in flexural mode and the cracks are generated from the tension zone to the compression zone and also the compressive strength greater than before due to decrease in porosity, as the fineness of fly ash enhanced.
