Many reinforced concrete (RC) structures are built around coastal areas or above the sea, which has very high risk of corrosion. Steel reinforcement corrosion in RC structures can cause failure of structural if not taken into account. Therefore, in this research, it is very important how durable oil palm shells (OPS) in corrosive area. One way to determine the durability of concrete without damaging it is to use the non-destructive testing method, which in this research uses the resistivity method. The method can evaluate the durability of concrete due to corrosion in OPS concrete. The effect of the percentage addition of OPS (10%, 20%, 30%, and 40%) and the addition of corrosion level (0.5%, 1%, 1.5%, 2%, 3%, and 4%) were also analysed. The results show that adding an oil palm shell (OPS) and the corrosion rate with natural and impressed current methods reduce the flexural strength of the concrete and the value of the resistivity of the concrete. The results show that adding an oil palm shell (OPS) and the corrosion rate with natural and impressed current methods reduce the flexural strength of the concrete and the value of the resistivity of the concrete. The resistivity value decreases along with the addition of the corrosion rate on each specimen.
