Corrosion testing of reinforced concrete block or slab specimens by cyclic chloride ponding as reported in NCHRP 244 and ASTM G109 for example has been widely employed for ranking or qualifying different reinforcements and for projecting service performance. However experimental issues such as inadequate bar end isolation ponding bath leakage and inappropriate specimen design can result in data that misrepresents long-term service performance. Further the fact that most testing protocols employ a 15 wt% NaCl solution can lead to erroneous ranking of corrosion resistant reinforcement and false projection of service performance. The present study discusses these issues and provides options whereby accelerated test data that more realistically represents service performance can be realized.
