Experimental Study on Bondanchorage of Highstrength Stainless Steel Wire in Polymer Mortar/Cao Jun,Wang Zhihao(Department of Civil Engineering,Tsinghua University,Beijing 100084,China)
Abstract:The highstrength steel wires bonding performance when anchoring in the polymer mortar through tensile experiment is studied.Through discussing about the experimental data and summarizing the character of the bonding behavior,the calculating formula of anchorage length is found.
Keywords:highstrength stainless steel wire; polymer mortar; anchorage length; bonding strength
