High-water-content material and preparation method thereof
The invention belongs to the technical field of coal mine gob-side entry retaining and gob filling, and particularly relates to a high-water-content material and a preparation method thereof. The high-water-content material comprises a material A, a material B and an auxiliary material, the material A comprises cement; the material B comprises gypsum and lime; the cement comprises one or more of 725 cement, 525 cement or 425 cement; the auxiliary material comprises one or more of sodium carbonate, lithium carbonate, citric acid, boric acid, bentonite or rubber powder. The preparation method comprises the following steps: mixing a material A, a first auxiliary material and water to obtain a first mixture; mixing the material B, a second auxiliary material and water to obtain a second mixture; mixing the first mixture and the second mixture, and stirring to obtain a mixed solution; and pouring the mixed solution into a mold, standing, solidifying and demolding. By adjusting the proportion of the ingredients, the problems that the solidification time is short after single slurry of an existing high-water-content material or ultrahigh-water-content material is stirred, the solidification time is long after the slurry is mixed and stirred, and the final strength is low are solved.
本发明属于煤矿沿空留巷及采空区冲填技术领域，具体涉及一种高水材料及其制备方法。本发明高水材料包括：A料、B料和辅料；A料包括水泥；B料包括石膏和石灰；水泥包含725水泥、525水泥或425水泥中的一种或多种；辅料包含碳酸钠、碳酸锂、柠檬酸、硼酸、膨润土或胶粉中的一种或多种。本发明的制备方法包括：将A料、第一辅料和水混合，获得第一混合物；将B料、第二辅料和水混合，获得第二混合物；将第一混合物和第二混合物混合，搅拌得混合溶液；将混合溶液倒入模具，静置，凝固脱模后即得。本发明通过调整配料的比例，解决了现有高水材料或超高水材料单浆液搅拌后凝固时间较短、浆液混合搅拌后凝固时间长，导致最终强度低的问题。
