Study on the influence of copper tailings on the performance of ultra-high performance concrete with packing structure optimization
To address the issue of copper tailings storage safely and environmentally,ultra-high performance concrete(UHPC)with packing structure optimization is used to recover copper tailings.The results show that the addition of copper tailings can increase the packing density of UHPC.Simultaneously,the study investigates the influence of copper tailings on the workability,mechanical properties,durability and hydration products of UHPC,and the leaching performance of heavy metal ions in copper tailings in UHPC is also considered.This study provides a way to reduce the leaching of heavy metal ions from copper tailings and to use copper tailings safely and environmentally.
