尾矿微粉用作建筑材料的性能研究

STUDY ON PERFORMANCE OF TAILINGS POWDER USED FOR BUILDING MATERIALS

主要对尾矿微粉作为水泥活性混合材及混凝土掺和料进行可行性试验。尾矿微粉经过特殊工艺处理深度加工而成。根据试验结果,与粉煤灰相比,普通尾矿粉、特制尾矿微粉作为水泥混合材及混凝土掺合料,其性能优于粉煤灰,尤其是特制尾矿微粉性能更优,为尾矿用作建筑材料提供可行性依据,真正实现了提高尾矿综合利用的目标。

In this paper,a series of experiments to study the possibility of using tailings powder as cement mixture material and admixture of concrete were designed. Tailings powder is processed through special craft processing. Besed on the test results,normal powder and specialized powder as cement mixture material and admixture of concerte have better performance than the fly ash,especially the specialized powder. This research provides the feasibility basis for tailings as building material,and realized the goal of improving the comprehensive utilization of tailings.
