Abstract

Concrete is still the most popular building material because it is cheap and doesn't catch on fire. Hardened cement, fine aggregate and coarse sand are combined with admixtures to create the final product. To meet the necessity of advanced infrastructure, new innovative materials and technologies have evolved; one such technique is adding fibre reinforced polymer composites as both internal and external reinforcement. Glass fibre polymer is becoming more popular for strengthening and fixing things because it is strong for its weight, doesn't wear out quickly, doesn't cost much to maintain, and doesn't rust. Fiber-reinforced polymer laminates are used to improve the flexibility and bending strength. Both small and large cracks can be stopped by fibres. The main focus of the investigation was to look at the efficiency of discrete GFRP wraps in improving the flexural strength of beams. Alcofine and steel fibres were added to the beams before it is wrapped with GFRP to replace the cement and also to take care of the serviceability of the beam. An experimental investigation was done on the conventional beam and GFRP wrapped alcofine beams to determine their load carrying capacity. These tests were administered on standard beam of 120*180*2000 mm for 28 days to see the behavior of the concrete element. Materials were tested and compared with conventional concrete beams in terms of strength and deflection. It is found from the experimental results that with wrapping up of the yielded concrete beam with GFRP had a significant increase in the flexural strength when compared to the conventional concrete element.
