The rebound method and core drilling method, as the main methods for testing concrete strength, each have their own advantages and disadvantages.
The rebound method is easy and fast to operate, but it is susceptible to various factors such as the surface condition and age of the concrete; The core drilling method yields intuitive and accurate results, but it may cause damage to the structure.
Therefore, comparing and analyzing the results of these two testing methods at different age groups in the article is helpful for a more comprehensive understanding of the variation law of concrete strength and providing scientific basis for engineering quality control.
