Underwater non-dispersive quick-setting grouting plugging composite material and preparation method thereof
The invention provides an underwater non-dispersive quick-setting grouting plugging composite material, and belongs to the technical field of grouting construction. The material comprises sulphoaluminate cement, water, a thickening agent, a composite water reducing agent, a composite clay mineral stabilizer and a flocculating agent, wherein the thickening agent accounts for 0.5%-1.5% of the weightof the sulphoaluminate cement, the composite water reducing agent accounts for 0.8%-1.2% of the weight of the sulphoaluminate cement, the composite clay mineral stabilizer accounts for 1.6%-2.0% of the weight of the sulphoaluminate cement, and the flocculating agent accounts for 1.5%-2.0% of the weight of the sulphoaluminate cement. The invention also provides a preparation method of the underwater non-dispersive quick-setting grouting plugging composite material. The material provided by the invention has the advantages of good anti-dispersion effect, short and adjustable setting time, faststrength increase, good slurry fluidity and stability, and obvious grouting plugging effect.
本发明提供一种水下不分散速凝灌浆堵漏复合材料，属于灌浆施工技术领域。所述材料包括硫铝酸盐水泥、水、增稠剂、复合型减水剂、复合型粘土矿物稳定剂、絮凝剂；所述增稠剂占硫铝酸盐水泥重量的0.5～1.5％，所述复合型减水剂占硫铝酸盐水泥重量的0.8～1.2％，所述复合型粘土矿物稳定剂占硫铝酸盐水泥重量的1.6～2.0％，所述絮凝剂占硫铝酸盐水泥重量的1.5～2.0％。本发明还提供所述水下不分散速凝灌浆堵漏复合材料的制备方法。本发明材料具有抗分散效果好、凝结时间短且可调、强度上升快，浆液流动性和稳定性好，灌浆堵漏效果明显。
