On Detection Technologies of Pre-Stressed Duct Grouting Fullness

Abstract:

Aging and deterioration (such as weakening of concrete strength and loss of prestress) of various degree will inevitably happen to prestressed concrete beam in service. In making the prestressed concrete beam, it is of vital importance to ensure that the prestress tension is sufficient, duct grouting is compact enough and concrete pouring is in good quality. Otherwise, structure will deteriorate faster and safety hazard and even bridge collapse may ensue, causing considerable economic losses.
