Mine high-water-content sludge cementing and curing material and preparation method thereof
The invention discloses a mine high-water-content sludge cementing and curing material and a preparation method thereof, and relates to the technical field of mine sludge curing. The concrete is prepared from the following components in parts by weight: 60-70 parts of fine aggregate, 25-30 parts of a cementing material and 5-10 parts of an additive, wherein the cementing material is prepared by compounding, mixing and grinding blast furnace water-quenched slag, yellow phosphorus slag, sulphoaluminate cement clinker, quick lime, purified phosphogypsum and water glass. The raw materials of the cementing material are mixed and ground by a grinding machine, and are uniformly mixed with the fine aggregate and the additive by a stirring machine to prepare the sludge cementing and curing material. The cementing material is subjected to a mixed grinding process, all the raw materials are in full contact in the mixed grinding process to generate a physical activation effect, the obtained cementing material is large in specific surface area and better in cementing and curing effect, and under the same condition, the mixed grinding performance is improved by 15%-20% compared with common mixing and cementing performance; in the process, drying is carried out to obtain the cementing material with lower water content, the use requirement of the high-water-content mine sludge is met, the mine sludge is treated through cementing and curing, and harmful elements in the sludge can be effectively fixed.
本发明公开了一种矿山高含水淤泥胶结固化材料及其制备方法，涉及矿山淤泥固化技术领域。由下列组分组成：60‑70份的细骨料，25‑30份的胶固料，5‑10份的外加剂；其中，胶固料由高炉水淬渣、黄磷炉渣、硫铝酸盐水泥熟料、生石灰、净化磷石膏、水玻璃复配混磨而成。将胶固料各原料使用磨机混磨后，与细骨料、外加剂经搅拌机混合均匀后制得淤泥胶结固化材料。胶固料使用混磨工艺，在混磨过程中各原料充分接触，发生物理活化作用，得到的胶固料比表面积大，胶结固化效果更好，相同条件下，混磨比普通混合胶结性能提高15％‑20％；过程中进行烘干得到含水率更低的胶固料，满足高含水矿山淤泥的使用要求，胶结固化治理矿山淤泥，能有效地固定淤泥中的有害元素。
