Karst grouting material and preparation method thereof
The invention discloses a karst grouting material and a preparation method thereof. The karst grouting material is prepared from the following raw materials in parts by weight: 10-50 parts of a composite activator, 20-70 parts of modified superfine slag powder, 30 parts of cement clinker, 60-100 parts of water and 1 part of a polycarboxylate superplasticizer, wherein the composite exciting agent is a mixture of modified electrolytic manganese residues, chlor-alkali industrial waste residues and cement clinker, and the weight ratio of all the components is 25: 3: 4. The prepared karst grouting material is high in strength, large in fluidity, moderate in setting time, good in impermeability and good in manganese and ammonia nitrogen curing effect, and the preparation process is simple.
本发明公开了一种岩溶注浆材料及其制备方法，岩溶注浆材料由以下重量份原材料制成：复合激发剂10‑50份，改性矿渣微粉20‑70份，水泥熟料30份，水60‑100份，聚羧酸减水剂1份；其中，复合激发剂为改性电解锰渣、氯碱工业废渣和水泥熟料的混合物，各组分重量比为25：3：4。本发明制备的岩溶注浆材料强度高，流动度大，凝结时间适中，防渗性好，固化锰和氨氮的效果好，且制备工艺简单。
