Shield synchronous grouting material and preparation method thereof
The invention discloses a shield synchronous grouting material and a preparation method thereof. The shield synchronous grouting material provided by the invention comprises the following components in parts by mass: 4-180 parts of cement; 12 parts to 255 parts of a mineral admixture; 40 to 180 parts of polishing slag; 100 parts to 300 parts of fine aggregate; 0 to 0.6 part of an additive; and 0 to 292 parts of water. The preparation method of the shield synchronous grouting material comprises the following step: uniformly mixing the cement, the mineral admixture, the polishing slag, the fine aggregate, the additive and the water to obtain the shield synchronous grouting material. The shield synchronous grouting material is good in stability and water-retaining property and small in segregation and bleeding risk, resource utilization of the polishing residues is achieved, and the treatment energy consumption of the polishing residues and the production cost of the shield synchronous grouting material are reduced.
本发明公开了一种盾构同步注浆料及其制备方法。本发明的盾构同步注浆料包括以下质量份的组分：水泥：4份～180份；矿物掺合料：12份～255份；抛光渣：40份～180份；细骨料：100份～300份；外加剂：0份～0.6份；水：0份～292份。本发明的盾构同步注浆料的制备方法包括以下步骤：将水泥、矿物掺合料、抛光渣、细骨料、外加剂和水混合均匀，即得盾构同步注浆料。本发明的盾构同步注浆料的稳定性和保水性好，离析泌水的风险小，且实现了抛光渣的资源化利用，降低了抛光渣的处置能耗和盾构同步注浆料的生产成本。
