Micro-expansion grouting material for grouting with mold and preparation method thereof
The invention provides a micro-expansion grouting material for grouting with a mold. The micro-expansion grouting material for grouting with the mold is prepared from the following raw materials in parts by mass: 430-470 parts of cement, 57-63 parts of sulphoaluminate cement, 57-63 parts of silica fume, 100-120 parts of fly ash, 90-110 parts of mineral powder, 162-178 parts of quartz sand, 34-38 parts of a water reducing agent, 0.6 part of an expanding agent, 0.2 part of cellulose, 0.2 part of a defoaming agent, 1 part of lithium chloride and 77.4-94 parts of water, wherein a mass ratio of thewater to the mixture of the cement and the sulphoaluminate cement is 0.18-0.2. By means of the micro-expansion grouting material for grouting with the mold, the expansion rate of the grouting material can be increased, lining disengagement is avoided, and tunnel safety is improved.
本发明提供一种带模注浆微膨胀注浆材料，该带模注浆微膨胀注浆材料由以下质量份数的原料组成：水泥430‑470份、硫铝水泥57‑63份、硅灰57‑63份、粉煤灰100‑120份、矿粉90‑110份、石英砂162‑178份、减水剂34‑38份、膨胀剂0.6份、纤维素0.2份、消泡剂0.2份、氯化锂1份、水77.4‑94份，所述水与所述水泥和硫铝水泥的混合物的质量比介于0.18‑0.2。通过本发明提供的带模注浆微膨胀注浆材料，能够提高注浆材料的膨胀率，避免衬砌脱空，提高隧道安全性。
