CORROSION OF REINFORCEMENT

Steel in good concrete does not corrode. However the fact that the problem of obtaining adequate quality for the concrete has not always been solved satisfactorily is evidenced by the failures due to rebar corrosion which can be seen around. Although rules have been developed over the last twenty years for the control of concrete quality, and hence durability, for given situations a failure to appreciate the reason for these rules has on occasion lead to failure of a structure. A closer examination of the basis of the rules may enhance their appreciation. When remedial measures are necessary then techniques for the detection of the extent of rebar corrosion without disruption of the concrete become important, if the remedial measures are to be confined to those areas where corrosion has actually occurred. It is equally important that techniques should be developed for the detection of corrosion before there are any visible signs on the surface. Although such techniques are not yet fully developed work currently in progress suggests that such techniques will become available in the near future. (Author/TRRL)
