Fly Ash is one of the major waste materials available from thermal power plants. Its treatment and disposal was a problem in the early stages. Researchers found out a useful method of replacing fly ash for cement in calculated qualities.Here an experiment has been conducted to study the performance of concrete using fly ash as the major binding material without of cement. Low calcium fly ash is preferred as a source material than High calcium fly ash because of to reducing more carbon di-oxide emission. Alkaline liquid Sodium hydroxide and Sodium silicate solution are used in this project as binders. It is used in Geo polymerization process.A mix proportion for Geopolymer concrete was designed and tests were carried out. The compressive, tensile & flexural strength of Geopolymer concrete have been studied and compared with OPC.Glass is one of the cheapest & abundantly available fibers. Glass fiber has been extensively used in reinforced cement. Glass fibers were added to the mix in fractions of 0.5%, 1%,1.5% and 2% to the weight of cement. Based on the test results, optimum % were formulated with respect to compressive,tensile & flexural strength
