Pre-activated clay-fluoroaluminate cement-based grouting material and preparation method thereof
The invention discloses a pre-activated clay-fluoroaluminate cement-based grouting material and a preparation method thereof, and relates to a grouting material and a preparation method thereof. The mass ratio of the component A to the component B is (0.4-0.7): 1, the component A is prepared from the following raw materials in parts by mass: 197-199 parts of silty clay and 1-3 parts of strong base, and the component B is prepared from the following raw materials in parts by mass: 30-60 parts of cement, 15-30 parts of fly ash, 10-20 parts of mineral admixture, 8 parts of thixotropic agent and 4-10 parts of water-resistant dispersant. The strength of a stone body can be improved, the setting time is short, the strength is rapidly increased, the stability is high, the bleeding rate is extremely low, and the performance requirement of reservoir dam crack plugging grouting is met.
一种预活化粘土‑氟铝酸盐水泥基注浆材料及制备方法，涉及一种注浆材料及制备方法。组分A和组分B的质量配比为0.4～0.7:1，组分A由以下质量份的原料组成：粉质粘土197～199份和强碱1～3份，组分B由以下质量份的原料组成：水泥30～60份、粉煤灰15～30份、矿物掺合料10～20份、触变剂8份和抗水分散剂4～10份。能够提高结石体强度，并且凝结时间短、强度增长快、稳定性强、析水率极低，满足水库大坝裂缝封堵注浆的性能要求。
