변형경화형 시멘트 복합체와 콘크리트 합성 슬래브의 균열제어 성능
윤현도(Yun, Hyun-Do),로쿠고(Rokugo, R.),임승찬(Lim, Sung-Chan),박완신(Park, Wan-Shin) 한국구조물진단유지관리학회 2009 한국구조물진단학회 학술발표회논문집 Vol.2009 No.1
This paper describes the crack-damage mitigation performances of RC(Reinforced Concrete) slabs layered with SHCC(Strain-Hardening Cementitious Composites). Three RC slabs with 1,800mm length, 400mm width and 180mm thickness were made and loaded monotonically to failure. Test variable is SHCC layer thickness(20 and 40mm). For the purpose of this study, a 1.5 percent(by volume) polyethylene(PE) fiber reinforced cement was selected as the material for the SHCC layer. The test results indicated that SHCC as a replacement for concrete that surrounds the main reinforcement in RC slabs would be possible to limit crack widths and enhance flexural performance.
