EVALUATION OF EFFECT ON REPAIR OF SECTION REPAIR METHOD OF CONSTRUCTION BASED ON REINFORCING BARS MASS DECREASE RATE OF THE LONG-TERM EXPOSURE TEST BODY

This paper reports the results of outdoor exposure test on the repair performance on corrosion of reinforcing bar in salt containing concrete by various repairing materials. When there is much chlorination amount of material in the concrete, effect on repression of the reinforcing bars corrosion by the repair method of construction can't be expected very much. When the repair of the section repair part is done, that countermeasure is important from showing a tendency of progressing in the part of the boundary remarkably as for the reinforcing bars corrosion after the repair. If chipping isn't taken to the back of the reinforcing bars, the effect of rust is prevented material, section repair material, When chlorination amount of material increases, corrosion spreads out in surface direction and depth direction as well.
