Road inorganic binder based on copper tailings, preparation method and application
The invention discloses a road inorganic binding material based on copper tailings, a preparation method and application, and relates to the technical field of copper tailings utilization, the road inorganic binding material based on copper tailings comprises the following components by weight: 25-35 parts of slag powder, 15-25 parts of Portland cement, 45-65 parts of fine aggregate, 15-20 parts of coarse aggregate, 10-20 parts of an activator and 4-10 parts of an early strength agent; the fine aggregate adopts copper tailings, the copper tailings are produced by a graded dehydration process, the sulfur content is 0.61%, and the proportion of the copper tailings is about 20% when the copper tailings are graded to be less than 75 microns. The mineral slag powder and ordinary Portland cement are adopted as cementing materials, the alkaline activator is added, water is added, high cohesiveness is achieved, copper tailings and coarse aggregate are effectively adsorbed, the cohesiveness of the copper tailings road inorganic binder is improved, the binding force between a road base and other interfaces is enhanced, and the workability of the copper tailings inorganic binder is improved.
本申请公开了基于铜尾砂的道路无机结合料、制备方法及应用,涉及铜尾砂利用技术领域,基于铜尾砂的道路无机结合料,包括以下按重量份数计的组分:矿渣粉25~35份,硅酸盐水泥15~25份,细骨料45~65份,粗骨料15~20份,激发剂10~20份以及早强剂4~10份;所述细骨料采用铜尾砂,所述铜尾砂为分级脱水工艺产出的铜尾砂,含硫含量为0.61%,其分级75μm以下占比约20%。采用矿渣粉以及普通硅酸盐水泥作为胶凝材料,添加碱性激发剂,加水后有较高的粘聚性,有效地吸附铜尾砂以及粗骨料,提高铜尾砂道路无机结合料的粘聚性,增强道路基层与其他界面间的粘结力,提高铜尾砂无机结合料的可施工性能。
