THE EFFECT OF STRAY CURRENT ON THE PROCESS AND THRESHOLD CONCENTRATION OF CHLORIDE ION CAUSING STEEL BAR CORROSION

摘要：

In this paper, the methods of stimulated concrete pore solution and loaded direct currentwcrc used to stimulate the corrosion environment of stray current and chloride ion coexistenceto research the effect of stray current on chloride ion threshold concentration causing steel barcorrosion. The results indicated that stray current had influences on the process of chlorideion-induced steel bar corrosion. The chloride ion threshold concentration of induced steel barcorrosion was related with not only alkalinity of pore solution, but also stray current intensityundcr stray current and chloride ion coexistence environment. The chloride ion thresholdconcentration decreased as stray current intensity increased. The relationship of chloride ionthreshold concentration between alkalinity of pore solution and stray current intensity wasbuilt.
