METHOD FOR INHIBITING STEEL MATERIAL CORROSION OF RC STRUCTURE
PROBLEM TO BE SOLVED: To provide a method for inhibiting the steel material corrosion of a RC structure, capable of inhibiting the corrosion of a steel material buried by an inexpensive and simple method without damaging, as much as possible, the RC structure including chloride ions.SOLUTION: A method for inhibiting the steel material corrosion of an RC structure, capable of inhibiting the corrosion of a steel material buried in the RC structure (a box beam 2 of a box beam bridge 1) comprises a pressure difference permeation step of permeating a liquid containing a corrosion inhibitor for inhibiting the corrosion of the steel material at a pressure difference using a suction pump (a vacuum pump P) from the surface of the RC structure (a base plate 20 of the box beam 2).SELECTED DRAWING: Figure 4
