ajst-13398	Zheng, Jingmin; Liu, Yingli	Concrete Non-destructive Testing Technology and Its Application	2023	3	.pdf	application/pdf	2561	93	39	There are many non-destructive testing methods, and different testing methods focus on different concrete properties, so it is very important to choose the right testing method for concrete testing. Classification of NDT techniques As concrete material is a complex mixture of materials, its components and the proportion of each component will affect the concrete performance, researchers boring also in acoustic, optical, electrical and physical properties of many areas of non-destructive testing technology, so produced a number of non-destructive testing methods.	cache/ajst-13398.pdf	txt/ajst-13398.txt
