Wei Wang 교수의 연구실은 콘크리트의 내구성과 구조적 거동을 중심으로, 부식 영향, 알칼리-활성화 시멘트, 복합재료의 상호작용, 화재 후 거동 등 다양한 환경 조건에서의 콘크리트 거동을 체계적으로 연구하고 있습니다. 특히, 첨가재료(석회석재, 사질자갈, 도시재료 등)의 영향과 복합재료의 미세구조적 특성 분석을 통해 내구성 향상 및 지속 가능한 콘크리트 기술 개발에 기여하고 있습니다. 연구는 실험적 분석과 미세구조 분석을 융합하여, 실제 구조물의 안전성과 수명 연장에 기여하는 기초 자료를 제공합니다.

Abstract Reinforcing steel bar can exert its strength and ductility by bonding to concrete. However, corrosion of steel bars reduces the bonding effect. This study mainly investigated the coupling effects of fly ash (FA) and corrosion on bond behavior. The impressed current method was utilized to achieve the target corrosion degrees. Three crucial factors that have impact on bond behavior was considered, which were FA content, corrosion degree and stirrups. The bond behavior was discussed using
Alkali activated materials (AAMs) have received worldwide attention due to its lower embodied energy and environmental impact than that of traditional cementitious materials. However, the activators with high alkalinity may raise the risk of alkali silica reaction (ASR) induced deterioration when reactive aggregates are used, which thereby limits the commercial use of AAMs. Not speaking the ASR induced long-term expansion, the early-age reaction of AAMs prepared with reactive aggregates is large
Abstract Fires frequently affect building structures, yet the mechanical behavior of deep flexural members, especially after exposure to high temperatures, remains inadequately understood. Current design codes for concrete structures at ambient temperatures do not sufficiently account for the residual capacity of these members following fire‐induced damage. Given the specific and complex mechanical properties of deep flexural members, particularly under varying shear span and shear‐depth ratios,
