Reinforcement Effect of CaCl₂ on Cementation Performance of Solid-Waste-Based Cementitious Materials for Fine Tailings by Qing Liu, Yanan Wu

“…The cemented fine tailings backfill can be hardened only after curing for ~36 h, with a 50% decrease in hardening duration compared to the control sample without CaCl₂. The optimal amount of CaCl₂ was controlled at 1.5 wt.%, and the sample strength reached 0.21 MPa at 36 h, even at a low binder-to-tailings ratio of 1:8, meeting the requirement of early strength of common cemented tailings backfills. …”
