“…Some parts of column 1 (especially lower part), column 2, and lower part column 4 were categorized into low corrosion risk level for the year 2014. In 2015, the corrosion risk level for those parts became intermediate risk level The increasing of corrosion risk level of the columns was consistent with the previous study conducting the half-cell potential mapping in Banda Aceh city, Indonesia [6] as seen in Figure 11(a). The indication of repassivation also occurred in the previous study that was shown in Figure 11(b) [6].…”

“…Many researchers have performed and justified the method to evaluate the reinforcing steel corrosion in concrete [3,[5][6][7][8]. Figure 1 shows the comparison of half-cell potential technique result to the actual condition of corrosion from the previous study [5] in which the half-cell potential technique result was consistent with the actual corrosion.…”

“…The infrastructures were repaired and reused again. Therefore, the infrastructures might be susceptible to corrosion attack [2,3] that can cause a decrease in strength [4], and sudden collapse may happen when an earthquake occurs even on a small scale [5,6]. This is certainly not desirable because, besides the material loss, it can also lead to loss of life of people.…”

The earthquake and tsunami of 26 December 2004 caused the infrastructure in Aceh's West Coast region to be submerged by seawater and to require the rehabilitation and reconstruction. The infrastructure that was submerged in the tsunami might experience a decrease in strength due to corrosion attack and would unexpectedly collapse if an earthquake occurs even on a small scale. This study was conducted to examine the corrosion risk level of the infrastructures in Aceh's West Coast region, Indonesia, which submerged by the 2004 tsunami. Three locations were chosen for the study, i.e., Suak Ribee, Ujong Kalak, and Padang Seurahet. The assessments were carried out in 2014 and 2015. Three to four columns in each of the buildings were selected for the assessment. The half-cell potential technique method which refers to ASTM C876 was used to obtain and analyze the assessment data. The results of the assessment show that the electrical potentials on the surface of concrete for the buildings which submerged by the tsunami were range between -100 and -450 mV (vs. Cu/CuSO 4 ) and categorized into low to high corrosion risk level. Meanwhile, the electrical potentials for new buildings range between (-100) and (-350) mV which indicated low to medium corrosion risk. Hence, the corrosion actively occurred in the areas having medium to high corrosion risk. Also, it was found that the corrosion risk level for the building tends to increase by increasing time. Therefore, the prevention and/or rehabilitation is necessary for stopping the corrosion, and so the premature failure of the building might be avoided.
