Cement-based grouting material as well as application and grouting method thereof
The invention provides a cement-based grouting material, and relates to the technical field of building materials. The cement-based grouting material provided by the invention comprises modified cement-based slurry and additive slurry which are independently subpackaged, the modified cement-based slurry comprises cement, a water reducing agent and water; the additive slurry comprises an aggregation agent, a water reducing agent and water. According to the invention, the water reducing agent is added into the cement, so that the performance of the cement is improved; meanwhile, an aggregation agent, a water reducing agent and water are independently prepared into additive slurry, so that an ideal flowing effect is achieved; admixture slurry and modified cement-based slurry are independently subpackaged, and are mixed during grouting, so that the aims of more accurately controlling the setting time of the grouting material and enhancing the short-term strength are fulfilled. The result of the embodiment shows that the cement-based grouting material provided by the invention has the properties of short final setting time and high short-term compressive strength at the same time.
本发明提供了一种水泥基灌浆料，涉及建筑材料技术领域。本发明提供的水泥基灌浆料，包括独立分装的改性水泥基浆液和外加剂浆液；所述改性水泥基浆液包括水泥、减水剂和水；所述外加剂浆液包括集结剂、减水剂和水。本发明通过在水泥中加入减水剂，对水泥性能进行改良；同时通过将集结剂、减水剂和水单独配置成外加剂浆液，使其达到理想的流动效果；通过将外加剂浆液与改性水泥基浆液独立分装，灌浆时再进行混合，以期达到更精准控制灌浆料凝结时间、增强短期强度的目的。实施例结果表明，本发明提供的水泥基灌浆料同时具有终凝时间短和短期抗压强度高的性能。
