以水玻璃作激发剂,磷石膏、粉煤灰、钢渣与矿粉作胶凝材料,盾构泥砂为细集料,并用聚羧酸系抗泥型高效减水剂和抗水分散剂改善浆料性能;通过对粉料比例、激发剂掺量等的研究,制得工作性能好(初始流动度27cm、6h后23.5cm,3h泌水率<1%),凝结时间长(>60h),抗水分散(水陆强度比>85%),可防止管片上浮(稠度值11.3cm)的高性能工业废渣-盾构泥砂同步注浆材料,并在武汉轨道交通3号线八B标段双王区间站取得了成功应用。
Water glass as an activator, phosphogypsum, fly ash, steel slag and mineral powder as a binder, shield silt fine aggregate, and polycarboxylate anti-mud type superplasticizer and water dispersant to improve the pulp (Initial fluidity 27cm, 6h after 23.5cm, 3h bleeding rate <1%), coagulation time is longer (> 60h), coagulation time is longer High-performance industrial waste slag-shield silt synchronous grouting material that can prevent the pipe from floating (consistency value of 11.3cm) can be prevented from dispersing by water (water-land strength ratio> 85% Wang interval station has been successfully applied.
