适用于狭窄空间及长距离灌浆作业的水泥基灌浆材料
摘要：
本发明涉及一种适用于狭窄空间及长距离灌浆作业的水泥基灌浆材料及其制备方法。所述适用于狭窄空间及长距离灌浆作业的水泥基灌浆材料，按质量份计，其原料包含：砂100份；水泥60～70份；矿物掺合料20～40份；膨胀剂5～10份；复合减水剂0.5～1份；触变防沉剂0.2～0.4份；和消泡剂0.1～0.3份。本发明的水泥基灌浆材料兼具持续扩展流动能力和低粘度性能，流动性能同时满足GB/T50448-2008中I类灌浆材料流动度要求的流动度≥380mm和ASTM-C939流出时间要求的流出时间≤35s，可为狭窄空间及长距离灌浆作业提供更为有效的解决方案。
摘要（英）：

The invention relates to a cement-based grouting material applicable to narrow-space and long-distance grouting operation and a preparation method thereof. The cement-based grouting material applicable to narrow-space and long-distance grouting operation comprises the following materials in parts by weight: 100 parts of sand, 60-70 parts of cement, 20-40 parts of mineral admixture, 5-10 parts of expanding agent, 0.5-1 part of compound water reducer, 0.2-0.4 part of thixotropic anti-settling agent, and 0.1-0.3 part of defoaming agent. The cement-based grouting material disclosed by the invention has continuously expanded fluid ability and low viscosity, and flowing property simultaneously satisfies fluidity not less than 380mm of fluidity requirements of grouting materials I in GB/T50448-2008 and flow time not more than 35 seconds of ASTM-C939 flow time requirements, therefore, a more effective solution can be provided for narrow-space and long-distance grouting operation.
