 This research paper examined the effect of various factors on the performance of superfine tailings cemented-paste backfill, SCPB. It found that the slump and slump flow of SCPB slurry decreases as the mass concentration increases due to the higher viscosity and yield stress of the slurry. Additionally, the strength of SCPB is primarily affected by the curing temperature, curing time, mass concentration, and cementisand ratio. The curing temperature has the greatest impact on the strength of SCPB, as it influences the hydration reaction rate of SCPB. This slower hydration process in a low-temperature environment leads to fewer hydration products in the looser structure, resulting in lower strength. These findings provide valuable insights into how to optimize the use of SCPB in alpine mines. This article was authored by Yufei Hu, Keqingli, Bo Zhang, and others.
