During on-site concrete strength testing, the rebound core correction method is more commonly used, while the rebound test block correction method is less commonly used.
How to deal with the situation where the standard curing and test blocks under the same conditions are met for the construction project mentioned earlier, but the rebound strength is insufficient? As introduced, there are generally three tests for compressive strength of concrete during the construction process: standard curing test blocks during inspection batch acceptance, same condition curing test blocks during sub acceptance, and engineering quality supervision sampling during main structure acceptance (mainly using rebound method for testing, and a small amount of core drilling is used for “verification” of foundation raft and other materials that cannot use rebound method).
