PENGARUH SALINITAS AIR LAUT TERHADAP NILAI POTENSIAL PROTEKSI ANODA DENGAN METODE ICCP
Reinforced concrete is a material consist of concrete and reinforce steel which is applied as a building and bridge structure. Based on its usefulness, reinforced concrete lies in a highly corrosive medium that is in seawater.Corrosion is reduction of the quality or destruction of a metal reacts with its environment. The process of corrosion in reinforced concrete in the seawater environment can be caused by pH, temperature, and salinity. Salinity of sea water ranges from 32 - 37 0/00. This research was conducted to determine the effect of salinity of seawater to potential value of anode protection on reinforced concrete by ICCP method. The study was divided into three environmental conditions with 32 0/00, 34 0/00, and 36 0/00NaCl, stainless steel304 as anode, and used a reference electrode Cu / CuSO4 with protection potential standard of -350 mV(ASTM C 876-91)for measuring the potential value of its protection. From the measurement results it is known that concrete in the environment of 36 0/00NaCl has a relatively larger current requirement to be able to protect compared to reinforced concrete in the environment of 32 0/00NaCl and 34 0/00NaCl. Thus the potential value of protection by anode in the environment of 36 0/00NaCl is higher than 32 0/00NaCl and 34 0/00NaCl.Corrosion rateof 32 0/00NaCl are 5.2 mpy, corrosion rateof 34 0/00NaCl are 6.8 mpy, and corrosion rateof 36 0/00NaCl are 17.9 mpy. Based on weight loss test and mpy comparison table with equivalent metric-rate corrosion (NACE International, 2002) the corrosion rate at the three salinity conditions included good level with range between 5-20 mpy. Keywords: Corrosion Rate, Reinforced Concrete, ICCP, Salinity, Stainless Steel304.
