Influence of Industrial By-Products on Durability of Fiber Reinforced Concrete

The concrete structures on coastal areas are suffering from chloride attack for decades. By using high performance concrete the deleterious effects on these structures can be minimized. Durability of concrete has been largely studied in order to prevent steel corrosion of concrete reinforcement for the production of new concrete structures in severe environments. Both liquid and gas permeability are main responsible character, lead to the deterioration of concrete and corrosion of the reinforcement. Hence various researchers suggested performing Electrical Resistivity Test, Ultrasonic Pulse Velocity Test, Acid Attack Test and Carbonation Test against the durability of the concrete. In this research durability of concrete is improved by replacing cement partially with silica fume up to 40% and sand partially with pond ash upto 20% by weight simultaneously with introduction of glass fiber of 0.1%. The method is based on the idea that the development of cracks formed by aggressive environments can be resisted by glass fiber.
