When choosing a method for monitoring the compressive strength of concrete, it’s important for project managers to consider the impact each technique will have on their schedule. While some testing processes can be done directly onsite, others require extra time for third-party facilities to deliver strength data. Time is not the only factor that contributes to project managers’ decisions. The accuracy of the testing process is just as important, as it directly effects the quality of the concrete structure.
There have been many developments to speed up the curing process since this testing method was first introduced. This includes the use of heating blankets, additives and vapor retarders. However, contractors still wait three days after placement before testing for strength, even though their targets are often reached much earlier than that.
Despite knowing that, many project managers prefer to stick to this testing practice because it’s “the way its always been done.” That doesn’t mean this technique is the fastest and most accurate method, however, for testing the strength of all placements. In fact, there are many different practices aside from cylinder break tests that can be used. Here are seven different approaches to consider when choosing a method of strength testing.
