this waste material is in concrete production because of its pozzolanic properties. Silica fume improves the characteristics of both fresh and hardened concrete. It was also found that it also reduces the permeability of the concrete to chloride ions, thus protecting the steel reinforcement present in concrete from the harmful effects of corrosion. Thus, this waste material is found to be ...
