Mining high-water high-strength filling material and preparation method thereof
The invention discloses a mining high-water high-strength filling material and a preparation method thereof. The mining high-water high-strength filling material is prepared from, by mass, a componentA and a component B. The component A includes, by mass, 50-70 parts of sulphoaluminate cement, 5-10 parts of fly ash, 1-10 parts of sodium bentonite, 1-5 parts of retarder and 1-5 parts of suspendingagent; and the component B includes: 5-10 parts of gypsum powder, 2-5 parts of quick lime, 1-5 parts of kaolin, 5-30 parts of quartz powder and 1-10 parts of a composite additive; and the raw materials of the component A and the component B are mixed in proportion and uniformly stirred to obtain the mining high-water-content high-strength filling material. The prepared material has the advantagesthat the setting time can be adjusted from ten minutes to several hours, and the compressive strength is high.
本发明公开了一种矿用高水高强度充填材料及制备方法，矿用高水高强度充填材料的制备原料包括A组分和B组分，以质量份数计，A组分包括：硫铝酸盐水泥50‑70份，粉煤灰5‑10份，钠基膨润土1‑10份，缓凝剂1‑5份，悬浮剂1‑5份；B组分包括：石膏粉5‑10份，生石灰2‑5份，高岭土1‑5份，石英粉5‑30份，复合添加剂1‑10份，将A组分和B组分的原料按比例混合，搅拌均匀，即得到矿用高水高强度充填材料。本发明所制备材料具有凝结时间可由十分钟至数小时调节，抗压强度高的优势。
