【Abstract】 Direct transmission method is applied to experiments on the bonding behavioe of new-to old concrete interfaces in repair specimens and reinforced concrete beams.It has been found that there is a close correlation between the bonding behavior of new-to-old concrete interfaces and the ultrasonic pulse velocity adopted,on the basis of which is put forward a feasible method for evaluating the bonding behavior of new-to-old concrete interfaces by means of ultrasonic pulse velocity.更多还原
