Corrosion Inhibition of Rebar in Seawater-Sea Sand Concrete by MWCNTs/LDHs-NO2

doi:10.16552/j.cnki.issn1001-1625.2024.1487

Abstract

Abstract: A novel composite material—multi-walled carbon nanotube/nitrite intercalated layered double hydroxide composites (MWCNTs/LDHs-NO₂) was prepared using an electrostatic self-assembly method. The inhibitory effect of MWCNTs/LDHs-NO₂ on rebar corrosion in seawater-sea sand concrete under constant current accelerated corrosion was investigated through chloride ion adsorption experiments, open circuit potential (OCP), electrochemical impedance spectroscopy (EIS), rebar weight loss measurements. The results show that the composite of nitrite-intercalated layered double hydroxide and multi-walled carbon nanotubes effectively enhances the chloride ion adsorption capacity of the material, and its adsorption follows the Langmuir adsorption model, with a maximum adsorption capacity of 218.5 mg/g. Electrochemical testing reveals that the application of MWCNTs/LDHs-NO₂ in concrete can protect the passivation film of rebar, slowing down the corrosion process. After 12 d of accelerated corrosion by electric current, the weight loss rate of rebar in samples containing MWCNTs/LDHs-NO₂ is 62% lower compared to the samples without MWCNTs/LDHs-NO₂ added. Therefore, MWCNTs/LDHs-NO₂ can effectively enhance the corrosion resistance of rebar in concrete.

Key words: MWCNTs/LDHs-NO₂, corrosion inhibitor, rebar, corrosion, seawater-sea sand concrete
