　　Live discussion

"Technical Regulations for Non-destructive Testing of Prestressed Hole Grouting Compactness Shock Elastic Waves" is the first domestic customized pre-targeted customized Association inspection regulations for the detection of grouting compactness of stress concrete bridges have an important role in guiding the normative development of the inspection industry.

"Technical Regulations for Field Nondestructive Testing of the Elastic Modulus of Concrete Structures" is a method and evaluation method for detecting concrete structures with elastic modulus as the core index after investigating and analyzing the current state of concrete structure inspection in China. Through the formulation of this regulation, on the one hand, the construction quality of the industry can be greatly improved, and on the other hand, it can promote the healthy development of the inspection industry.
