This paper describes the results of a laboratory investigation into factors which influence the performance of the tendon/grout interface in grouted rock anchors containing threaded bars. Parameters investigated include confining stiffness, grouted length and expansive cement content. Test results show that the strength of the interface increases with increasing confining stiffness and expansive cement content and decreases as the grouted length increases. Explanations for the observed results are presented, and a simple model for predicting the change in performance with grouted length is briefly described.
