Grouting filler composition, grouting filler, application of grouting filler and composite elbow gap filling method
The invention relates to the field of grouting, and discloses a grouting filler composition, a grouting filler, application of the grouting filler composition and a composite elbow gap filling method. The grouting filler composition comprises the following components in parts by mass: 100 parts of fly ash, 600 to 1750 parts of Portland cement, 30 to 150 parts of an expanding agent, 1 to 10 parts of a water reducing agent and 2 to 12 parts of a coagulant, and the content of the Portland cement is 600 to 1750 parts by mass, the content of the expanding agent is 30 to 150 parts by mass, and the content of the water reducing agent is 1 to 10 parts by mass and the content of the coagulant is 2 to 12 parts by mass. All the components of the grouting filler composition have a synergistic effect, the prepared grouting filler is high in flowability, free bleeding rate is zero, the shrinkage rate is smaller than or equal to 2%, the compressive strength is larger than or equal to 16 Mpa, larger than or equal to 21 Mpa and larger than or equal to 25 Mpa after grouting is conducted for 3 days, 7 days and 28 days, and the grouting filling rate is 90% or above by volume.
本发明涉及灌浆领域，公开了一种灌浆填充料组合物、灌浆填充料及其应用与复合弯管缝隙填充方法。灌浆填充料组合物包括粉煤灰、硅酸盐水泥、膨胀剂、减水剂和促凝剂，其中，以所述粉煤灰的含量为100质量份计，所述硅酸盐水泥的含量为600‑1750质量份，所述膨胀剂的含量为30‑150质量份，所述减水剂的含量为1‑10质量份，所述促凝剂的含量为2‑12质量份。该灌浆填充料组合物各组分之间协同作用，制得的灌浆填充料流动性大、静置2h无分层现象、自由泌水率为零，且收缩率≤2％，灌浆后3d、7d和28d的抗压强度分别为≥16Mpa、≥21Mpa和≥25Mpa，灌浆填充率为90体积％以上。
