After the completion of concrete pouring, when various participating units have doubts about the quality of the concrete, or before the completion of the project sampling inspection, it is necessary to conduct physical testing of various indicators of the concrete to verify whether it meets the requirements of various design indicators.
The specific number of tests will be determined based on the testing purpose and the actual situation of the project.
The main quality inspection index for concrete entities is compressive strength, and two commonly used methods are core drilling method and rebound method.
