Tóm tắt

Bond behavior between the reinforcement steel bars and surrounding concrete is considered as an important characteristic for reinforced concrete structures, including lightweight aggregate concrete ones. This paper presents an experimental investigation on the bond behavior of 14 mm diameter steel bars embedded in lightweight aggregate concrete. The bond slip relationship between rebar and lightweight aggregate concrete shows a conventional behavior, similar to traditional reinforced concrete. The development length of 14 diameter steel embedded in lightweight aggregate concrete is smaller than the requirement in ACI 318-11.
