Monitoring corrosion of steel bars in reinforced concrete

2020-2-1  Steel bar corrosion not only reduces the load-carrying capacity owing to the reduced cross section of the bar, but also degrades the concrete-steel interface and causes concrete cracking. It is significant to monitor the corrosion condition of steel bars in reinforced concrete to ensure the safety and effective asset management.

Table 3 Monitoring Corrosion of Steel Bars in Reinforced

This corrosion activity had been monitored to evaluate the effect of leaching on carbonation and corrosion initiation of steel bars. Observed that with the increase in leaching exposure carbonation depth also increases. Replacing cement partially with fly ash reduces the resistance against carbonation and leaching.

2017-9-11  Measuring the chloride content in concrete cover (and at the rebar surface) is a classic method in corrosion investigation of concrete structures. Powder samples are obtained from different depths (usually 5 depths from exposed surface to rebar level), and chloride profile is developed. Diffusion coefficient can be determined in this method.
