Abstract: As we know Plain Concrete has limited ductility, strength in tension as well as low cracking resistance. Micro cracks are present in concrete and these propagates at a great extent and results in extensive brittle fracture. Experiments in past and numerous researches in the last decade were focused merely on developing novel techniques of improving tensile strength of concrete. Among these mostly used is GFRP (Glass Fiber Reinforced Polymer) is easily available, which is low in cost than CFRP (Carbon Fiber Reinforced Polymer), and that’s why various studies is done to strengthening of concrete by using GFRP particularly in countries like India. GF is latest introduction cum revolution in production FRC. It overpowers all the synthetic fibers, due to its excellent strength, extreme durability, supreme wear-tear resistance and exceptional tensile and impact strength. At this time GFRC (Glass Fiber Reinforced Concrete) excelled as a great remedy for civil engineers. Tensile strength of GFRC lies between 1024 and 4080 N/mm2 . It is the benefit of using glass fibers in reinforcement of concrete. Construction Industry is accelerating day-by-day. Today is the scenario of sky scrapping and complex infrastructures, which results in increasing demand of basic civil engineering material i.e. cement. Engineers are looking for alternative of expensive construction since long. Cement, binder in concrete, is an expensive and exorbitant civil engineering material and it increases the Constructional budget. Not only this, but also cement marks the highest consumption throughout the world after water. The carbon credits to the environment during cement production, is an alarming issue. If it keeps following the exact pace as today, it is probable to reach annual cement production up to about 600 metric tons by 2025 in India alone and the globe will change into hot air balloon. Cement industry alone contribute to 2.4% to the total carbon emissions round the globe. To eradicate this converse effect of cement industry on the environment, engineers are working hard to find efficient substitutes which are in-expensive, eco-friendly and can possess better cementing properties. Agricultural and commercial wastes are the best choice and have the characteristics favouring their utilization in concrete production. These by-products are complete waste and if re-used in any sort releases a huge burden from environment. Keywords: Glass Fiber, Workability, Compressive strength, Compaction factor, Slump test
