在结构混凝土质量的现场检测中,强度测量和缺陷探测是两个不可分割的组成部分。目前,强度的非破损或半破损检测问题已有较多的研究,尽管这些研究还只能建立在标准强度与各种测试指标(如声速、回弹、拔出强度、芯样强度等)的经验关系之上,但所建立的经验关系毕竟给出了明确的数值结论。然而,关于缺陷的探测,虽然近年来也进行了大量研究,提 In the on-site inspection of structural concrete quality, strength measurement and defect detection are two inseparable components. At present, the strength of non-damage or half-damage detection problems have been more research, although these studies can only be based on the standard strength and a variety of test indicators (such as sound speed, rebound, pull-out strength, core strength, etc.) On the basis of empirical relationships, the established empirical relationships, after all, give clear numerical conclusions. However, with regard to the detection of defects, many studies have been conducted in recent years.
