混凝土非破损测试与传统的破坏检验法相比,有如下优点: 1.不破坏混凝土结构就能检验它的质量,并且速度快,又能重复测试。 2.应用超声法还可以检验混凝土内部的质量,如孔洞大小、裂缝深度和范围,可以检验受到诸如火灾、冰冻、化学介质的腐蚀,以及地震后混凝土质量的受损程度等。 3.当混混土试块强度不合格时,或对混混土结构物质量有异议时,采用非破损法直接对结构进行检验,可以确定它的质量状况。 4.长龄期混凝土建筑物的改建或加层,在缺乏原始资料时,可采用非破损法对构件进行检验,确定工程混凝土的实际承载能力。前国家建委在1978年将混凝土非破损检
The non-destructive test of concrete has the following advantages compared to the traditional damage inspection method: 1. The quality of a concrete structure can be verified without destroying the concrete structure, and the test can be repeated. 2. Ultrasound can also be used to inspect the quality of concrete inside, such as hole size, crack depth and extent, and can be tested for damages such as fire, freezing, chemical media, and damage to concrete quality after an earthquake. 3. When the strength of the mixed soil test block is unqualified, or when there is objection to the quality of the mixed-mixed soil structure, the non-damage method is used to directly inspect the structure and its quality can be determined. 4. In the case of reconstructing or adding layers to long-term concrete buildings, in the absence of original data, non-damage methods may be used to inspect the components to determine the actual bearing capacity of the concrete. The former National Construction Commission will test the non-breakage of concrete in 1978
