| 摘要: |
| 探讨了甲基纤维素对新拌水泥浆体若干性能的影响，并将其与水灰比和水泥品种的影响进行了比较。结果表明：甲基纤维素有显著的增稠和提高水泥浆体保水性的作用，有较小的增塑、缓凝效果；甲基纤维素引气效果明显，因此应用中需特别考虑其对材料强度的影响。 |

| Abstract: |
| In comparison with the effect of mass ratio of water to cement and types of cement, the influence of methyl cellulose(MC) on properties of fresh cement paste was experimentally investigated. The results show that MC can improve the consistency and water retentivity of fresh cement paste significantly, increase the fluidity and setting time of cement slightly. Further, it can increase the air content of mixtures significantly, so the decrease of strength must be considered while adding it to cementitious materials. |
