Active powder grouting material and preparation method thereof
The invention discloses an active powder grouting material and a preparation method thereof. The grouting material is prepared from the following raw materials in parts by mass: 38 to 41 parts of Portland cement, 50 to 54 parts of fine aggregate, 5 to 5.4 parts of superfine fly ash, 7 to 7.6 parts of silica fume, 0.5 to 2.0 parts of steel fiber, 0.3 to 0.4 part of a water reducing agent and 0.02 to 0.03 part of an expanding agent. The active powder grouting material disclosed by the invention has the characteristics of good fluidity, no shrinkage, compression resistance, fracture resistance, high splitting tensile strength and the like, and the raw material components are safe, non-toxic and environment-friendly, so that the active powder grouting material has relatively high practical value and good application prospect.
本发明公开了一种活性粉末灌浆料及其制备方法。所述灌浆料的原料组成及质量份配比如下：硅酸盐水泥38~41份，细骨料50~54份，超细粉煤灰5~5.4份，硅灰7~7.6份，钢纤维0.5~2.0份，减水剂0.3~0.4份，膨胀剂0.02~0.03份。本发明所述活性粉末灌浆料具有流动性好、无收缩、抗压、抗折、劈裂抗拉强度高等特点，且原料组分安全无毒环保，具有较高的实用的价值和良好的应用前景。
