混凝土超声波无损检验主要应用于以下诸方面:探测建筑物内部缺陷及裂缝;测定建筑物的强度及均匀性;研究水泥混凝土的性能等等。一、用超声脉冲法探测混凝土的内部缺陷由于施工控制不良,往往在建筑物内部造成孔洞、架空、蜂窝等缺陷。如何探测它,以为补救措施提供依据,这无疑是一个有实际意义的问题。 Concrete ultrasonic non-destructive testing is mainly used in the following areas: detection of internal defects and cracks in buildings; determination of the strength and uniformity of buildings; study of concrete properties and so on. First, the ultrasonic pulse method to detect the internal defects of concrete due to poor construction control, often resulting in the building holes, overhead, honeycomb and other defects. How to detect it in order to provide a basis for remedial measures is undoubtedly a matter of practical significance.
