- Abstract
- In this present study, the corrosion mitigation effect of conifer cone extract (CC) was examined in the cement mortar to improve the steel rebar (SR) corrosion resistance. The corrosion inhibition properties of the SR embedded in cement mortar (CM) admixed with different percentage (0, 0.5, 1.0, 1.5, 2.0 %) of CC was studied by open circuit potential (OCP) and electrochemical impedance spectroscopy (EIS) tests. This result confirms that the CM with 0.5% of CC added has better corrosion resistance than the blank specimen (0 % of CC). Although, the percentage of CC increase above 0.5%, the CC could yield a negative impact on CM properties in terms of reducing the corrosion resistance due to the reduction of cement hydration reaction. It was highlighted that the SR embedded in CM containing 0.5% of CC had increased corrosion resistance.
