工程实例充分表明了超声回弹综合法的可靠性,该法利用声速和回弹两个物理量来推定混凝土强度,较为全面客观地反映了影响混凝土强度的各种因素,提高了无损法检测混凝土强度的精度。加之该法操作相对简单、经济性较好,是一种实用方便的混凝土无损法检测方法。 The engineering examples fully demonstrate the reliability of the ultrasonic rebound method. The method uses the two physical quantities of sound velocity and springback to estimate the strength of concrete, which reflects the various factors affecting concrete strength in a comprehensive and objective way, and improves the strength of concrete by non-destructive method The accuracy. Coupled with the method of operation is relatively simple, better economy, is a practical and convenient concrete non-destructive method of detection.
