Study on Anchorage Performance of New High-Strength Fast Anchorage Agent

To achieve the efficient, rapid construction of prestressed anchor cables, in this study, through an indoor pull-out test and field basic test, we investigated mechanical behavior, expansion, drawing performance bond properties a new type high-strength, fast anchorage agent. We analyzed influence water material ratio curing time on its determined corresponding construction. It was found that anchoring agent could be effectively applied achieved compressive strength 30 MPa within h. Moreover, during solidification process, hydration reaction node reached 5–6 h when expansion feedback to water–material were strongest. In addition, exhibited strong with reinforcement rock layer, bonding layer greater than steel bar. Therefore, order provide anchorage, it is necessary increase contact area between strand
