Controllable low-strength material based on shield slurry and regenerated sand powder as well as preparation method and application of controllable low-strength material
The invention discloses a controllable low-strength material based on shield slurry and regenerated sand powder as well as a preparation method and application of the controllable low-strength material. The controllable low-strength material based on the shield slurry and the regenerated sand powder comprises a cementing material, compound regenerated sand powder, the shield slurry, a water reducing agent, a coagulant and water, wherein the compound regenerated sand powder is formed by compounding regenerated sand powder with the particle size of 0.075-0.30 mm, regenerated sand powder with the particle size of 0.30-1.18 mm and regenerated sand powder with the particle size of 1.18-4.75 mm. The preparation method of the controllable low-strength material comprises the following steps: uniformly mixing the cementing material, the compound regenerated sand powder, the shield slurry, the water reducing agent, the coagulant and the water. The controllable low-strength material is high in fluidity, high in stability and controllable in strength, bleeding is avoided while high fluidity is guaranteed, and the controllable low-strength material is simple in preparation process and low in cost and has remarkable social benefits and economic benefits.
本发明公开了一种基于盾构泥浆和再生砂粉的可控性低强度材料及其制备方法与应用。本发明的基于盾构泥浆和再生砂粉的可控性低强度材料的组成包括胶凝材料、复配再生砂粉、盾构泥浆、减水剂、促凝剂和水，复配再生砂粉由粒径0.075mm～0.30mm的再生砂粉、粒径0.30mm～1.18mm的再生砂粉和粒径1.18mm～4.75mm的再生砂粉复配而成。本发明的可控性低强度材料的制备方法包括以下步骤：将胶凝材料、复配再生砂粉、盾构泥浆、减水剂、促凝剂和水混合均匀。本发明的可控性低强度材料的流动性高、稳定性高、强度可控，在保证高流动度的同时还避免了泌水，且其制备工艺简单、成本低廉，具有显著的社会效益与经济效益。
