摘要在盾构隧道壁后注浆工程中,选择合适的速凝剂,缩短壁后注浆浆体(浆体)的凝结时间,对控制地层沉降和管片上浮至关重要。采用Na₂CO₃和Li₂CO₃两种碱性速凝剂配制壁后注浆,分析了两者对浆体凝结时间、流动度经时损失和强度的影响规律及微观机制。结果表明:两类速凝剂均能明显缩短浆体的凝结时间,提高浆体强度,但同时导致浆体流动度经时损失加快。添加3%Na₂CO₃、0.5%Li₂CO₃分别使浆体凝结时间缩短至6.5 h和8 h,2.5 h后浆体流动度保持在220 mm,浆体14 d强度为3.8 MPa,相比未添加速凝剂浆体的强度提高30%以上。微观结构分析表明,碱性速凝剂通过与石膏和CH晶体反应,促进水泥矿物C₃A和C₃S水化,缩短了浆体的凝结时间;此外,碱性速凝剂促使水泥水化产生水滑石、方解石,并激发粉煤灰生成C-A-S-H,均使浆体结构更为致密,进而提高其后期强度。

关键词: 壁后注浆碱性速凝剂凝结时间流动度经时损失反应机理

Abstract: Appropriate accelerators were selected to reduce the setting time of grouting slurry, thereby controlling ground settlement and minimizing early segment flotation in backfill grouting of shield projects. Two typical alkaline accelerators, Na₂CO₃ and Li₂CO₃, were utilized in the preparation of backfill grouting, and their effects on setting time, fluidity loss, and slurry strength were analyzed. Experimental results demonstrated that both types of accelerators significantly reduced the setting time of the slurry and increased its strength. However, the loss of slurry fluidity over time also accelerated. By adding 3%Na₂CO₃ and 0.5%Li₂CO₃, the setting time was reduced to 6.5 hours and 8 hours, respectively, while the fluidity maintained at 220 mm after 2.5 hours. After 14 days, the slurry strength reached 3.8 MPa, which was more than 30% higher than that of the slurry without accelerators. Microstructure analysis revealed that the alkaline accelerators promoted the hydration of cement minerals C₃A and C₃S by reacting with gypsum and CH crystals, thus shortening the setting time of the slurry. Additionally, alkaline accelerators promoted the hydration of cement to produce hydrotalcite and calcite, and stimulated the formation of C-A-S-H from fly ash, all of which enhanced the density of slurry structure and thus improved later strength.

Key words: backfill grouting alkaline accelerator setting time fluidity loss over time reaction mechanism
