Through a series of experiments in including anodic polarization by mixing different dosage of corrosion inhibitor in sand mortar, the slump, loss of slump, set time, gas content of fresh concrete and compressive strength, durability experiment including impermeability and freeze-thaw resistance and the test of saline water immersion, it proved that mixing some FAC-13 corrosion inhibitor in concrete has no influence on the slump and loss of slump, set time, compressive strength as well as durability including the seepage height, the loss in weight and the relative dynamic elastic modulus, but the chloride diffusion coefficient, the corrosion ratio of reinforcements and the weight loss rate dropped obviously. It proves that the corrosion inhibitor has obvious antirusting effect on the steel bar and has applied successfully in real projects.
