| Abstract |
The evaluation method of structural concrete strength in present building construction field involves a lot of problems and difficulties. The reasons are, incase of destruction test by core collection, low use frequencies due to limitation of core collection and difficulties of execution, and impossibility of initial strength estimation. In case of strength test with management specimen, different environmentcompared to the structure environment cause problems about estimating precise structure strength. Therefore, it is required to develop structure direct strength test that has test values and credibility above the ones obtained by core specimen collection strength test and to eliminate experimental defects caused by easy execution and simple test methods. The management of concrete strength can be justified when credibility of structure strength is ensured by measuring the strength of structure concrete built in the construction field by joint separation technique that can directly assess structure strength without affecting the structure itself. The purpose of this research is to improve the product management method of structure concrete by building the stability and credibility of concrete product management. |
