Studies on the Evaluation Method of Strength Comparison for Application in Joint Separation Test Body to Structural Concrete

구조체 콘크리트에 접합분리 시험체의 적용을 위한 강도비교에 관한 실험적 연구

It has been reported that destruction test by core collection is the most reliable of the structural concrete strength in present building construction field. But it causes low efficiency by damage and cutting in structure due to the core collection. It also has some problems in repairing. Additionally in case of strength test with management specimen, different environment compared to the structure environment cause problems about estimation 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 seasonal specimen test to suggest a reasonable and practical management method of structural concrete.
