Abstract: In post-tensioned prestressed bridges, the grouting quality of prestressed ducts is of paramount importance to the durability and load-bearing capacity of the bridge. Voids within the ducts may allow water and other corrosive substances to penetrate, leading to corrosion of the steel reinforcement and ultimately affecting the structural safety of the bridge. Impact-echo (IE) testing, an effective non-destructive evaluation (NDE) method, enables scientific and accurate assessment of the grouting quality of grouting ducts in pre-stressed structures without damaging the structure. This paper examines the impact-echo method for assessing grouting quality in post-tensioned prestressed ducts, confirming its adaptability and reliability for practical engineering applications.
