It is globally known that structures exposed to corrosive environments can collapse due to deterioration of the steel rods embedded in the concrete. The corrosion-inhibition potential of leaves, bark, and root extracts of Boswelia dalzelia (BD) on concrete reinforcement was investigated using a half-cell potentiometer and scanning electron microscopy (SEM) analysis. The half-cell potential readings are generally negative, and the higher the magnitude of the negative value, the higher the probability of corrosion occurrence. Measurement of corrosion potential with a half-cell potentiometer is highly effective in determining the inhibition potential of green inhibitors in concrete reinforcements. For the concrete prisms treated with BD plants in an acid medium, the samples containing leaves, bark, and root extracts have potential readings ranging from -150 mV to -200 mV, -300 mV to -350 mV, and -350 mV to -400 mV, respectively. On the other hand, the samples treated with leaves, bark, and root extracts in chloride medium have potential readings ranging from -50 mV to -150 mV, -50 mV to -100 mV, and -250 mV to -300 mV, respectively. Scanning electron microscopy (SEM) results show that all protected samples had low corrosion, whereas the unprotected or control samples showed severe corrosion attack. In general, all samples treated with plant extracts showed reduced corrosion risk compared to the control samples.
