Glass Fibre Reinforced concrete (GFRC) is a recent introduction in the field of concrete technology. It has been extensively used in over 100 countries since its introduction in 1980’s. This product is covered by international standards and has been practiced all over the world. GFRC has advantage of being light weight and thereby reducing the overall cost of construction there by bringing economy in construction. This work is only an accumulation of information about GFRC from all over the internet and some text books. GFRC is concrete that uses glass fibres for reinforcement instead of steel. It is typically cast in a thin section of around ½Â” to ¾Â”. Since the fibres cannot rust like steel, there is no need for a protective concrete cover thickness to prevent rusting. With the thin, hollow construction of GFRC products, they can weigh a fraction of weight of traditional precast concrete.
