Abstract：This article uses concrete penetration depth,electrochemical impedance spectroscopy,linear polarization,and scanning electron microscopy to study the effect of amino alcohol migration repair rust inhibitor on the corrosion inhibition of steel bars in concrete.The results showed that the permeability of rust inhibitor SK in concrete was weaker than that of rust inhibitor ZX,and it could penetrate to 35～45 mm,while the penetration depth of rust inhibitor ZX was 55～60 mm.Adding amino alcohol migration rust inhibitors to the simulated pore fluid of concrete can inhibit corrosion of steel bars.When the ZX content is 6%,the rust prevention efficiency is 98.88%.When the SK content is 4%and 6%,the rust prevention efficiency is only 76.76%and 67.72%.Therefore,applying rust inhibitor ZX in concrete structures can better suppress steel corrosion.
