Corrosion of steel reinforcement results in early deterioration of reinforced concrete (RC) structures reducing its strength, durability and service life. Porous nature of concrete is responsible for chloride and moisture ingress initiating corrosion in RC elements. Materials like flyash and silica fume; by-product of industrial processes otherwise threat to the environment, are now-a-days commonly used in the construction industry for the preparation of concrete. Previous researches proved that it enhances mechanical properties of concrete. In the present study performance of concrete prepared by using flyash and silica fume is experimentally investigated for corrosion resistance of RC elements when exposed to aggressive environment for different exposure durations. The experimental results witness that use of silica fume and flyash as cement replacement material and increased curing duration not only enhances mechanical properties of concrete but also improves performance of RC element there by resisting corrosion in aggressive environment.
