재건축현장의 콘크리트 압축강도 조사

The purpose of this study was to analyze the compressive strength of concrete in comparison between nondestructive test done to the building which was to be demolished at residential reconstruction site and destructive test of core specimen from the site. The research result is more reliable because we can compare the measurement of nondestructive test with the result from destructive test by Universal Testing Machine. Schmidt Hammer Test was done for the columns, girder and slab inside and outside of the building. Compressive Strength of each material was calculated with the result of Schmidt Hammer Test. In addition, we performed Ultrasonic Test for another result of compressive strength. And we made a comparative study of compressive strength of concrete drawn from both nondestructive and destructive tests.
