✦ Synopsis

Influence of binder type on anodic dissolution of steel embedded in cement pastes with and without chloride is investigated by examination of anodic polarization curves. The results indicate that the formation of passive layer on steel embedded in cement paste is dependent on the type of binder used. In situation of chloride ion present in the mixing water, passive range is still observed at a concentration of 0.08 M NaC1. In the case of penetrating chloride, passive range of steel is either severely limited or not observed after 6 months of immersion in water with 0.02 M NaCI.

Dynamic polarization techniques were used to estimate the corrosion rates of steel embedded in cement paste made with different binder systems. A corrosion model is proposed. The corrosion rates were determined by employing the Evans diagrams constructed from cathodic polarization curve of steel emb

Two sets of neat paste samples, prepared with an ordinary Portland cement and a ternary blended cement (containing slag and fly ash), were stored in various corrosive solutions of different pH (11.5 and 13) and chloride concentrations (up to 20 g/1 of Cl'). Structural and textural alterations were i
