DB37/T 2368-2022

This document is applicable to the detection of the compressive strength of structural concrete using the core drilling method. When there are many components to be tested, the rebound method, the ultrasonic rebound comprehensive method, the post-installation pull-out method, etc. are used in combination with the core drilling method to form the core drilling correction method. The results of the core drilling method are used to correct the results obtained by other detection methods, making the detection results more reliable and reducing the damage to the structure.
