Sulphate attack of reinforcement steel in presence of mineral and chemical concrete admixtures

Abstract
Corrosion behaviour of reinforcement steel embedded in cement pastes incorporating different amounts of mineral and chemical admixtures has been studied in 5% Na2SO4 solution using different electrochemical techniques. The results show that, the reinforced steel embedded in cement paste incorporating silica fume with different amounts of chemical concrete admixtures, manifests a high degree of passivation on soaking the samples in the investigated medium. The effect of each admixture changes depending on its type and concentration.
