Formula and production process of drilling grouting double-fast expanding agent
The invention discloses a drilling grouting double-fast expanding agent formula and a production process thereof. The expanding agent is prepared from the following components in parts by weight: 40% of 425 Portland cement clinker, 40% of fly ash, 9.5% of quick lime, 10% of secondary smelting waste aluminum ash, 0.2% of sodium silicate, 0.2% of polyvinyl alcohol and 0.1% of aluminum powder paste. The double-fast swelling agent for drilling and grouting has the advantages of low cost and good effect. The double-fast swelling agent for drilling and grouting can effectively solve the problem of a drilling air leakage channel formed by shrinkage after drying after coal mine cement grouting and hole sealing; the double-fast expanding agent for drilling grouting and water are poured into a stirring barrel according to the ratio of 1: 0.5 to be uniformly stirred, and then are directly injected into a sealed drill hole by a grouting pump to expand and block the drill hole in the activation and sweat collection process within 1-2 hours, so that the effect of solid core hole sealing is achieved.
本发明公开了一种钻孔注浆双快膨胀剂配方及其生产工艺，膨胀剂由下述以重量份计的组分组成：425硅酸盐水泥熟料40%、粉煤灰40%、生石灰9.5%、二次熔炼废弃铝灰渣10%、硅酸钠0.2%、聚乙烯醇0.2%，铝粉膏0.1%。本发明具有成本低、效果好的优点，本发明钻孔注浆双快膨膨剂能有效的解决煤矿用水泥注浆封孔后出现的干后收缩形成的钻孔漏气通道；本钻孔注浆双快膨胀剂和水按1：0.5比列倒进搅拌桶搅拌均匀后，直接用注浆泵注进所封钻孔内在1～2小时内活化收汗过程中膨胀堵死钻孔而达到实芯封孔的效果。
