Gelling composite material as well as preparation method and application thereof
The invention discloses a gelling composite material as well as a preparation method and application thereof. The gelling composite material is prepared from the following raw materials in parts by weight: 30 to 80 parts of cement, 90 to 270 parts of mixed sand, 30 to 80 parts of slag powder, 6 to 18 parts of resin modified basalt fiber, 0.5 to 4 parts of natural fiber, 4.5 to 20 parts of inorganic nano material, 0.5 to 2.5 parts of water reducing agent, 0.2 to 0.5 part of air entraining agent and 14 to 45 parts of water, the mixed sand comprises superfine sand obtained by screening the dredging sludge, and the particle size of the superfine sand is less than 1mm. The gelling composite material disclosed by the invention has excellent breaking strength, compressive strength and crack resistance, realizes resource utilization of the slag powder and the ditch dredging sludge, and is suitable for repairing and reinforcing the drainage pipe of which the pipe is concrete.
本发明公开了一种胶凝复合材料及其制备方法和用途。所述胶凝复合材料包含如下重量份的原料：水泥30～80份、混合砂90～270份、矿渣粉30～80份、树脂改性玄武岩纤维6～18份、天然纤维0.5～4份、无机纳米材料4.5～20份、减水剂0.5～2.5份、引气剂0.2～0.5份、水14～45份；所述混合砂包含通沟污泥经筛分后得到的特细砂，所述特细砂的粒径＜1mm。本发明的胶凝复合材料具有优异的抗折强度、抗压强度以及抗裂缝性能，同时实现了矿渣粉与通沟污泥的资源化利用，适用于管材为混凝土的排水管的修复、加固。
