Low-temperature-resistant grouting material and preparation method thereof
The invention discloses a low-temperature-resistant grouting material and a preparation method thereof, relates to the technical field of grouting materials, and solves the technical problem that a grouting material in the prior art cannot adapt to a low-temperature environment. The low-temperature-resistant grouting material comprises, by weight, 450-750 parts of cement; 50-100 parts of an expanding agent; 1.0-4.5 parts of a water reducing agent; 0.2-1.0 part of a defoaming agent; 10-50 parts of calcium oxide; 70-100 parts of sodium sulfate; 30-50 parts of urea; and 40-60 parts of ethylene glycol. The low-temperature-resistant grouting material is suitable for being used at the low temperature of -5 DEG C or above.
本发明公开了一种耐低温压浆材料及其制备方法，涉及压浆材料技术领域，解决现有技术中存在的压浆料无法适应低温环境的技术问题，以各组分的重量份数计，包括以下组分：水泥450‑750；膨胀剂50‑100；减水剂1.0‑4.5；消泡剂0.2‑1.0；氧化钙10‑50；硫酸钠70‑100；尿素30‑50；乙二醇40‑60；本发明的耐低温压浆材料适合在‑5℃以上的低温下使用。
