저품질 콘크리트 강도 저하 원인에 따른 성능변화 및 이를 고려한 해체공사 구조 안전성 평가

Abstract

This study aims to investigate the insufficiency of concrete strength and the peculiarities of winter weather conditions in relation to on-site ready-mixed concrete, based on the standard mixture. By creating low-quality concrete and comparing it with standard concrete in terms of strength and absorption rate, the study seeks to provide indicators for the utilization of concrete structures. Additionally, in order to ensure safety during the dismantling of low-quality concrete structures, various load combinations and strength reductions are applied, and the structural safety is evaluated. The findings of this evaluation can serve as fundamental data for securing safety during dismantling operations, considering the dismantling methods and equipment used.
