Abstract The inhibition behavior of calcium lignosulfonate and sodium oleate for carbon steel in simulated concrete pore solution was studied. Calcium lignosulfonate showed good inhibition for steel in simulated concrete pore solution even after 7200 h immersion. The molecular simulation indicated that sinapyl alcohol in calcium lignosulfonate is the preferred site for accepting electrons. The microscopic infrared imaging showed that at the early stage of immersion the characteristic adsorption happened for calcium lignosulfonate at the corroded areas on the surface, which would be helpful for preventing initiation and propagation of both general and pitting corrosion.
