The invention discloses an anti-freezing low-temperature-resistant grouting material and a preparation method thereof. The grouting material is prepared from the following components in parts by weight: 300 to 750 parts of 42.5 Portland cement; 100 to 350 parts by weight of 42.5 sulphoaluminate cement; 100 to 300 parts of mineral admixture; 10 to 50 parts of silica fume; 10 to 50 parts of glass microbeads; 50 to 100 parts of expanding agent; 1.0 to 4.5 parts of a water reducing agent; 0.2 to 1.0 part of a defoaming agent; 50 to 150 parts of sodium nitrite; 10 to 30 parts of calcium nitrate; 0.3 to 1.5 parts of anti-settling powder; and 0.1 to 0.8 part of a suspension stabilizer. The grouting material disclosed by the invention has the characteristics of good slurry flowing property, no layering, no bleeding and fullness, does not shrink after being hardened, has high strength, and is particularly suitable for construction and use in a low-temperature environment of -5 DEG C or above.
本发明公开了一种防冻型耐低温压浆材料及其制备方法。以各组分的重量份数计，所述压浆材料包括以下组分：42.5硅酸盐水泥：300‑750；42.5硫铝酸盐水泥：100‑350；矿物掺合料：100‑300；微硅粉：10‑50；玻化微珠：10‑50；膨胀剂：50‑100；减水剂：1.0‑4.5；消泡剂：0.2‑1.0；亚硝酸钠：50‑150；硝酸钙：10‑30；防沉降粉：0.3‑1.5；悬浮稳定剂：0.1‑0.8。本发明的压浆材料具有浆体流动性能好，不分层，不泌水，充盈饱满的特点，硬化后不收缩、强度高，特别适用于‑5℃以上的低温环境下施工使用。
