Curing-free cement-based shrinkage-free grouting material
The embodiment of the invention discloses a curing-free cement-based shrinkage-free grouting material. The invention relates to a curing-free cement-based shrinkage-free grouting material, which consists of cement, slag powder, quartz sand and an additive, and further comprises an internal curing agent and an expanding agent, the internal curing agent is prepared from the following components in percentage by weight: 30 to 40 percent of water-absorbent resin, 20 to 30 percent of cellulose and 30 to 40 percent of suspension stabilizer; the expanding agent is prepared from the following components in percentage by weight: 15-25% of calcium oxide, 25-35% of calcium sulphoaluminate, 25-35% of gypsum and 15-25% of magnesium oxide. The grouting material disclosed by the invention does not need manual maintenance, saves a large amount of labor cost and time cost, greatly improves the working efficiency, improves the engineering quality, and has a relatively good application prospect.
本发明实施例公开了一种免养护水泥基无收缩灌浆料。一种免养护水泥基无收缩灌浆料，由水泥、矿渣粉、石英砂及外加剂组成，还包括内养护剂和膨胀剂；所述内养护剂按重量百分含量计，由30～40％吸水树脂、20～30％纤维素、30～40％悬浮稳定剂组成；所述膨胀剂按重量百分含量计，由15～25％氧化钙、25～35％硫铝酸钙、25～35％石膏、15～25％氧化镁组成。本发明的灌浆料无需进行人工养护，节省大量人力成本和时间成本，大大提高了工作效率，提高工程质量，具有较好的应用前景。
