High-fluidity early-strength cementing material as well as preparation method and application thereof
The invention discloses a high-fluidity early-strength cementing material as well as a preparation method and application thereof. The method comprises the following steps: uniformly mixing 100 parts by weight of aluminate cement, 2-20 parts by weight of quick lime and 0.1-20 parts by weight of gypsum, then adding 0.01-0.6 part by weight of a retarder, 0.01-0.5 part by weight of a water reducing agent and a proper amount of water, so that the water-cement ratio is 0.12-0.6, and uniformly mixing to obtain the cementing material. The cementing material provided by the invention is an early-strength cementing material with high flowability and controllable setting time, and can be used as a mine backfill material, a grouting reinforcement material, a mine water plugging material, a concrete 3D printing material and the like.
本发明公开了一种高流动性早强胶凝材料及其制备方法与应用。本发明公开的制备高流动性早强胶凝材料的方法包括如下步骤：将100重量份的铝酸盐水泥和2‑20重量份的生石灰、0.1‑20重量份的石膏均匀混合，然后加入0.01‑0.6重量份的缓凝剂、0.01‑0.5重量份的减水剂和适量的水，使得水灰比为0.12‑0.6，均匀混合，得到胶凝材料。本发明提供的胶凝材料是一种高流动、凝结时间可控的早强胶凝材料，可用作矿井回填材料、注浆加固材料、矿井堵水材料和混凝土3D打印材料等。
