研究了两种采矿选矿废渣对预拌砂浆性能的影响。结果表明:采矿选矿废渣替代部分天然河砂能提高预拌砂浆的保水性能,砂浆具有良好的工作性能。石粉对砂浆具有促凝作用。废渣颗粒形状对砂浆力学性能具有重要影响。
The effects of two kinds of mineral processing waste on the properties of ready-mixed mortar were studied. The results show that the replacement of part of natural river sand with mining dressing waste can improve the water holding capacity of ready-mixed mortar, and the mortar has good working performance. Stone powder on the mortar with procoagulant effect. The shape of waste particles has an important influence on the mechanical properties of mortar.
