DETERIORATION DUE TO CORROSION IN REINFORCED CONCRETE

Examples are given of cases of premature structural deterioration involving corrosion in reinforced concrete. In the majority of these cases chemical analysis indicated the presence in the concrete of chloride ions which have been deliberately introduced as the set accelerator calcium chloride. Occasional problems of concrete spalling associated with low cover to reinforcement, have also been observed. This paper discusses ways of assessing the deterioration caused by corrosion, methods of repairing the concrete, and implications for future design and construction. (TRRL)
