Glass Fibre Reinforced Concrete, GFRC


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. Glass Fibre Reinforced concrete (GFRC) has advantage of being light weight and thereby reducing the overall cost of construction there by bringing economy in construction. Glass Fibre Reinforced concrete (GFRC) derives its strength from a high dosage of Alkali resistant glass fibers and a high dosage of acrylic polymer. While compressive strength of Glass Fibre Reinforced concrete (GFRC) can be quite high due to low water to cement ratios and high cement contents, it is the very high flexural and tensile strengths that make it superior to ordinary concrete. While the structural properties of GFRC itself are superior to unreinforced concrete, properly designed steel reinforcing will significantly increase the strength of objects cast with either ordinary concrete or GFRC. This is important when dependable strength is required, such as with cantilever overhangs, and other critical members where visible cracks are not tolerable. GFRC does not replace reinforced concrete when true load carrying capacity is required. It’s best used for complex, three dimensional shells where loads are light. While the weight savings due to reduced thickness is maintained, the effort of forming, mixing and casting are similar or the same In present investigation concrete with addition of glass fiber and various proportions is studied to find the optimum dosage of Glass fiber for concrete. The results of Glass fiber reinforced specimens with various dosages of glass fiber are compared with control specimens to study the behavior of glass fiber reinforced concrete properties.
