Abstract:
Chloride-induced corrosion causes significant deterioration in transporta-tion structures where uncoated reinforcing steel is used. Concretes with a very low permeability are used to prevent the intrusion of chlorides into con-crete to the level of the reinforcing steel. This study evaluates the strength and permeability of various combinations of silica fume and slag in con-crete. It was determined that when silica fume is added in small amounts (3 to 5 percent) to concretes with up to 47percent slag at a water-cement ratio of 0.40 and 0.45, economical concretes with very low permeability and ad-equate strength can be produced.
