Experimental Study on Adhesion Performance between Ribbed Steel Bar and High-Strength Cement Soil
摘要
Abstract
[Objective]The aim of this study is to uncover the bonding mechanism between ribbed steel bars and high-strength cementitious soil.Thirty-three cubic pull-out specimens with dimensions of 150 mm×150 mm×150 mm were produced using an existing cementitious soil solidifier ratio.[Method]Through direct pull-out tests,the in-fluence of anchorage length,cementitious soil cover thickness,and steel bar diameter on the bonding perfor-mance between steel bars and cementitious soil was analyzed.[Result]The experiments indicate that the bond-ing strength at the interface between steel bars and cementitious soil decreases with the increase of anchorage length.The optimal cover thickness for steel bars and cementitious soil is between 2 to 3 times the diameter of the steel bar.[Conclusion]As the diameter of the steel bar increases,the impact of the diameter growth on the bonding strength decreases,especially when the diameter exceeds 10 mm.关键词
