AUXILIARY ANODE, CORROSION-PREVENTING CONSTRUCTION OF A CONCRETE STRUCTURAL BODY USING THIS, AND CORROSION PREVENTION METHOD

摘要

[Problem] To provide an auxiliary anode, corrosion-preventing construction of a concrete structural body using this, and a corrosion prevention method capable of preventing electrical corrosion, with little generation of gas due to electrolysis of water or chlorine compounds, by decreasing as far as possible the amount of processing performed on the structural body in on-site construction work and suppressing the voltage that is conducted therethrough to a low level. [Solution] A corrosion-preventing construction (1) is constituted by sticking an auxiliary anode (10) to the surface layer (3) of a corrosion-preventing body (4) through a first electrolyte layer (12) on one face of a conductive layer (11) formed as a sheet. The electrolyte is formed as a sheet. The first electrolyte layer (12) having tacky adhesivenessis stuck to the conductive layer (11) and the surface layer (3) of the corrosion-preventing body (4).
