摘要
采用超声波的首波幅度、接收波形及频率等声学参量判定混凝土板底面砂浆层是否存在粘结缺陷，并可确定缺陷的大小范围及严重程度．通过工程实例，阐述超声波测缺原理、检测方法及砂浆层粘结质量超声波检测技术的特点．
The amplitude of the first pulse, the waveform and frequency of the received pulse, and other ultrasound parameters were used to detect the bond defect between concrete slab and its finishing mortar, and to determine the size and extent of the defect. The principles and methods with ultrasonic technique to detect defect are described by some project examples. Also, the characters of using this technique to test the bond quality of mortar layer are described.
