| In the existing prestressed concrete bridges, remarkable corrosion and breakage of prestressing steels, which in turn reduces strength of the bridges themselves or may cause protrusion of tendon and injure pedestrian, due to imperfect grout is reported. Clarification of the mechanism of this kind of deterioration regarding grout quality is necessary in order for prestressed concrete technology to contribute to maintenance and development of infrastructure. In this paper, the effect of grout filling condition on corrosion of prestressing steel is studied through dissection research. |
