Process for preparing cement-based cementing material by utilizing sulfur-containing tailings
The invention discloses a process for preparing a cement-based cementing material by using sulfur-containing tailings. The process comprises the following steps: (1) firstly preparing activated desulfurized tailings; and (2) preparing the cured desulfurized tailings. And (3) preparing the cement-based cementing material. According to the technology, the problem of compatibility between the sulfur-containing tailings and the concrete material when the sulfur-containing tailings are used for preparing the concrete material is effectively solved, good curing of heavy metal elements in the sulfur-containing tailings is achieved, and the pollution problem caused by dissolution of the heavy metal elements from a concrete structure is relieved.
本发明公开了一种利用含硫尾砂制备水泥基胶凝材料的工艺，包括步骤：(1)先制备活化脱硫尾砂。(2)再制备固化脱硫尾砂。(3)制备水泥基胶凝材料。本发明的工艺有效克服了含硫尾砂在用于制备混凝土材料时两者之间的相容性问题，并实现了对含硫尾砂中重金属元素良好的固化，有助于缓解重金属元素从混凝土结构中溶出造成的污染问题。
