CONCRETE COATINGS: DO THEY REDUCE ONGOING CORROSION OF REINFORCING STEEL? CORROSION OF REINFORCEMENT IN CONCRETE. PAPERS PRESENTED AT THE THIRD INTERNATIONAL SYMPOSIUM ON "CORROSION OF REINFORCEMENT IN CONCRETE CONSTRUCTION", BELFRY HOTEL, WISHAW, WARWICKSHIRE, MAY 21-24, 1990
This paper reports an investigation of the effectiveness of a range of concrete coating and impregnant materials for stopping or reducing the rate of corrosion of steel in concrete. The types of material tested were: (a) a waterproof polymer cement slurry; (b) a solvent free urethane; (c) a liquid plastic dressing; (d) a silane/acrylic; and (e) an alkyl alkoxy silane. Their effectiveness was assessed on laboratory specimens by monitoring variations in corrosion current and potential of the steel, resistivity and chloride content of the concrete and the weight of the test specimens, before and after surface treatment of the concrete. None of the materials succeeded in stopping the corrosion. The alkyl alkoxy silane produced the largest average reduction (37 per cent) in corrosion rate. This reduction in corrosion current appeared to be caused by a small decrease in the moisture content of the concrete.(A) For the covering abstract of the conference see IRRD 831449.
