Accelerated Corrosion Testing Results for Specimens Containing Uncoated Reinforcing Steel and Corrosion Inhibitors

Concrete slabs containing uncoated reinforcing bars were cast with a concrete cover of 20 mm. The w/c was either 0.25, 0.40, or 0.60. A simulated crack 0.4-mm wide was formed transverse to the axis of the reinforcing bar. Three types of commercial corrosion inhibitors were added to concrete mixtures for corrosion protection. Slabs were placed in an accelerated exposure cabinet with 4 cycles of wetting/drying per day in simulated seawater. Corrosion rates were measured using the linear polarization technique. Some of the concrete slabs were broken open at the end of the exposure period and corrosion damage was evaluated. Water soluble chloride content analysis in the rebar trace was performed at the end of the exposure period for all the examined specimens. The various types of corrosion inhibitors showed a wide variation in performance and their effectiveness was also found to be particularly sensitive to addition rate. In general, all had a greater effectiveness in reducing corrosion rate in a higher w/c ratio concrete than in a lower w/c ratio concrete.
