Concrete is the world's most versatile, durable and reliable construction material. Next to water, concrete is the most used material, which required large quantities of Portland cement. Ordinary Portland cement production is the second Only to the automobile as the major generator of carbon di oxide, which polluted the atmosphere. In addition to that large amount energy was also consumed for the cement production. Hence, it is inevitable to find an alternative material to the existing most Expensive, most resource consuming Portland cement. Geopolymer concrete is an innovative construction material which shall be produced by the chemical action of inorganic molecules. Fly Ash, a by- product of coal obtained from the thermal power plant is plenty available worldwide. Flyash is rich in silica and alumina reacted with alkaline solution produced alumina & silicate gel that acted as the binding material for the concrete. It is an excellent alternative construction material to the existing plain cement concrete. Geopolymer concrete shall be produced without using any amount of ordinary Portland cement. This project reviews the constituents of geopolymer concrete, its strength and potential applications. The experimental conducted on processes flyash based geopolymer concrete in which ash is use as a source material instead of cement & two types of alkaline activators (NaOH solution of concentration of 13 moles & Na 2 SiO 3 solution) were used in geopolymer concrete cube of size 150x15x150 mm, cylinder 150 mm diameter &300 mm height, beam 750x150x150mm were casted by varying water to geopolymer binder ratio from 0.30, 0.35,0.40. With incremental of 0.05. The geopolymer concrete cube, cylinder, beam were cured in oven curing. In oven curing it was kept under 90 0 C for 24 Hours duration. Then it was tested for 7, 14, 28 days for compressive strength, flexural strength & indirect split tensile strength are conducted on each of 3 mixes. It was observed that water to cementious material of 0.30 the result are promising. The detailed investigation conclusion drawn from experimental work have been highlighted in this dissertation.
