摘要: |
对注浆加固公路路基用的水泥浆体从稳定性、流动度、粘滞度、凝结时间、析水率等方面进行了研究,掺加适量的粉煤灰可增加浆体的稳定性,外加剂水玻璃可增国浆体的稳定性及结石率,同时对浆体的流动性有降低作用,而外加剂氯化钙则对浆体的流动性有增强作用。 |

Abstract: |
In this paper, the behavior of grouting cement mortar to reinforce highway subgrade is analyzed from the aspects of stability, fluidity, viscosity, bleeding ratio and setting time of cement mortar. Mixing a certain content of fly ash to cement mortar can improve stability of mortar. Mixing water glass can improve stability and increase forming stone percent of mortar and can reduce the fluidity of mortar. While mixing CaCl 2 can increase fluidity of mortar also. |
