Abstract

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.
