Title:
CORROSION PREVENTION METHOD AND CORROSION PREVENTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/170828
Kind Code:
A1
Abstract:
The purpose of the present invention is to repair reinforced concrete in a simple manner at low cost. This corrosion prevention method comprises: a moistening step of causing a corrosion prevention solution 4 retained inside concrete 21 in reinforced concrete to permeate in the vicinity of reinforcing steels 22 through the concrete 21 to passivate the reinforcing steels 22; a detection step of detecting that the corrosion prevention solution 4 has permeated to a surface 25 of the concrete 21; and a drainage step of, subsequent to the detection of the corrosion prevention solution 4 in the detection step, draining the corrosion prevention solution 4 to the outside of the concrete 21 to form a corrosion-preventing coating film on the surfaces of the reinforcing steels 22.
