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.
Ferronickel slag is a by-product of the ferronickel extraction process. Smelting process that contain the oxide compounds such as SiO2, CaO, Al2O3, and Fe2O3. The compound content is similar to the content of Portland brand commercial cement (OPC) which is commonly used as raw material for making concrete. Therefore, this research will analyze the effect of using ferronickel slag as a cement mixture on the resistance of reinforced steel in concrete. The author will analyze the corrosion behavior of various mixtures of OPC cement and ferronickel slag with variations in the use of Ferronickel slag as much as 5%, 10%, 15%, 20% with OPC cement in the process of curing concrete for 28 days then it is immersed 3.5% NaCl solution. The concrete wiil uses cyclic polarization method to analyze pitting behaviour and resistance corrosion of reinforced steel in chloride environment. The results show that the steel in the 20% slag concrete mixture added with OPC cement has resistance compared to other mixed variations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
