摘要	Oleic acid was incorporated into concrete to observe its influence on the corrosion resistance of carbon steel in the presence of chloride ions. Penetration tests, concrete pore structure tests, electrochemical experiments and XRD tests were performed to study the inhibition and mechanism of oleic acid on reinforced concrete structures. The obtained results showed that oleic acid performed well in inhibiting the corrosion of carbon steel. The chloride penetrability test resulted in a decreased chloride migration coefficient value when oleic acid was added to the concrete. The increased potential from the open circuit potential test, the increased resistance of the concrete, the increased resistance of the charge transfer process from the electrochemical impedance spectroscopy measurement and the decreased corrosion current density from the polarization curve test revealed that the corrosion of the carbon steel in the concrete was slowed. XRD, the concrete pore structure and the contact angle analysis revealed that the inhibition was mainly due to the reaction of oleic acid and the hydration products of cement.
