一种易搅拌的超高强水泥基灌浆材料
摘要：
本发明涉及一种易搅拌的超高强水泥基灌浆材料，由以下物质按质量百分比组成：水泥40~50%，膨胀剂0.8~1%，增韧剂1~2%，流变助剂0.1~0.5/万，纳米二氧化硅2~4%，掺合料4~10%，超塑化剂0.1~0.3%，消泡剂1~3/万，黄砂35~50%。本发明的超高强水泥基灌浆材料出浆体状态时间短，可显著缩短搅拌时间，从而大幅提升施工效率和施工质量。
摘要（英）：

The invention relates to an ultrahigh strength cement-based grouting material easy to stir. The grouting material comprises the following substances by mass percent: 40-50% of cement, 0.8-1% of expanding agent, 1-2% of toughening agent, 0.1-0.5/ten thousand of rheological aid, 2-4% of nano-silica, 4-10% of admixture, 0.1-0.3% of super plasticizer, 1-3/ten thousand of defoaming agent and 35-50% of yellow sand. The ultrahigh strength cement-based grouting material has the beneficial effects that the duration of the slurry yielding state is short; the stirring time can be obviously shortened, thus substantially improving the construction efficiency and the construction quality.
