超声波速评价新老混凝土粘结质量的试验研究
|
摘要
采用透射法对修补小试块和修补梁的新老混凝土界面性能进行试验研究 ,发现超声波波速与界面粘结质量具有良好的相关性 .提出了用超声波速评定新老混凝土界面粘结质量的一种方法 .
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.
