Mining inorganic reinforcing material and preparation method thereof
The invention discloses a mining inorganic reinforcing material and a preparation method thereof, and relates to the technical field of inorganic materials. The mineral inorganic reinforcing material is prepared from the following raw materials in parts by mass: 420 to 480 parts of cement, 415 to 470 parts of mineral powder, 105 to 170 parts of gypsum, 160 to 200 parts of water and 16 to 20 parts of a water reducing agent. The raw materials are all inorganic materials, so that the defects that an organic reinforcing material is inflammable, toxic and easy to age are overcome. The 3d compressive strength of the mining inorganic reinforcing material is not less than 50MPa, the 7d compressive strength is not less than 75MPa, the early strength is high, and the mining inorganic reinforcing material is suitable for reinforcing mine fracture zones.
本发明公开了一种矿用无机加固材料及其制备方法，涉及无机材料技术领域。所述矿用无机加固材料的原料组成，按质量份数计，原料包括：水泥420‑480份、矿粉415‑470份、石膏105‑170份、水160‑200份和减水剂16‑20份。本发明原料全部采用无机材料，克服了有机加固材料易燃、有毒、易老化的缺陷。本发明矿用无机加固材料的3d抗压强度不小于50MPa，7d抗压强度不小于75MPa，早期强度高，适用于矿山破碎带加固。
