CORROSION OF REINFORCING STEEL IN CONCRETE CONTAINING SLAG OR POZZOLANS

Research is reported that evaluates the long-term corrosion-resisting characteristics of concrete incorporating pozzolans or slags. The effect of varying the cement content and water-cement ratio of both the plain and fly ash concretes in the corrosion of steel was investigated. The long-term corrosion-resisting characteristics of concrete samples made with 2 Class F fly ashes, a natural pozzolan, a blast-furnace slag cement, and a preblended portland-fly ash cement were evaluated. The materials are described and the results are presented and discussed. It was found that the corrsoion rates of reinforcing steel in pozzolanic cement and blast-furnace slag cement concretes are lower than the corrosion rates of steel bars in plain cement concretes. These and other findings are discussed.
