<P>PROBLEM TO BE SOLVED: To obtain a carbon fiber sheet in which gas is hard to be generated and having a uniform current distribution at the time of performing electrical protection to a concrete structure, and to provide an electrical protection structure and an electrical protection method where deterioration in an anode caused by the generation of gas is reduced, and electrical protection can be efficiently performed. <P>SOLUTION: In the carbon fiber sheet, each continuous single fiber composed of carbon is covered with an oxidation resistant metal. A beltlike fibrous strand formed of the plurality of continuous single fibers is organized so as to be a lattice shape with gaps. One side of each gap is about 2 to 20 mm. The gaps are arranged so as to be put at the intervals of the plurality of beltlike fibrous strands in parallel to the longitudinal direction, and also be put at the intervals of the plurality of beltlike fibrous strands in parallel to the horizontal direction. The carbon fiber sheet is laid on the surface of a concrete structure via cement mortar, the carbon fiber sheet is covered with the cement mortal, and a conducting means is connected with the carbon fiber sheet as the anode and steel in the concrete structure as the cathode. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
