Abstract: In the world most commonly used as well as durable material is concrete. In the field of concrete technology, glass fiber reinforced concrete (GFRC) is the recently introduced material. GFRC has many advantages such as light weight material, steel reinforcement corrosion free and structural deterioration free. So, these are the reason the researchers all over the globe are attempting to develop high performance concrete with the use of glass fibers as well as admixtures. While the combination of fly ash, alkaline liquids, fine and coarse aggregate and glass fibers resulted in the product called as Glass Fiber Reinforced Geopolymer Concrete (GFRGC). This product has many advantages such as high early strength, corrosion and sulphate resistance and low shrinkage. The present work has compared the compressive strength, split tensile strength and flexural strength for GFRC and GFRGC. From this comparison it is observed that except for the flexural strength the normal concrete with the addition of glass fibers shown good results as compared to the geopolymer concrete with the addition of glass fibers. This work is only an accumulation of information about GFRC and the research work which is already carried out by other researchers.
