摘要
通过试验研究在表面活性剂质量浓度不同的情况下,不同表面活性剂与磷酸-水玻璃混合浆液的胶凝时间、渗透性以及抗压强度的变化规律。通过模拟注浆试验,总结掺入不同表面活性剂的磷酸-水玻璃混合浆液注浆量以及结实体体积的基本规律。经综合考虑,不同表面活性剂质量浓度最佳值为4~6 g/L,3种表面活性剂与磷酸-水玻璃混合浆液中,掺入十二烷基苯磺酸钠的混合浆液性能表现最优。该研究结果可为实际注浆施工提供参考。
Under different concentrations of, the changing law of gelling time, permeability and compressive strength of phosphoric acid-sodium silicate slurry mixed with different kinds of surfactant was studied by experiments and the basic law was summarized by the simulation grouting test. Overall consideration is that the best surfactant concentration is 4 ~6 g/L. Among 3 kinds of surfactant with phosphoric acid-sodium silicate slurry, the slurry mixed with sodium dodecyl benzene sulfonate(SDBS) has the best performance. This study can provide references for actual grouting construction.
