Abstract
Tin slag is one of smelting waste that has not been utilized yet. As substitutional, cementious material in concrete replaced the function due to its similar oxide existence with Ordinary Portland Cement (OPC) such as SiO2, CaO, Al2O3, and Fe2O3. The objective of this research is to evaluate the corrosion behavior on the surface of carbon steel rebar due to the effect of partial substitution of tin slag in mortar. In this research, final tin slag added with ratio of 0.1, 0.2, 0.3 from total cement. The concrete had been cured for 28 days of immersed in NaCl 3.5% solution for 6 days. The corrosion behavior against steel reinforcement inside concrete measured by Electrochemical Impedance Spectroscopy (EIS) method and the result shows that 20% tin slag from the total of cement give the most competitive corrosion resistance than the others.
