| 摘 要： | 本文利用差热分析、X射线衍射、扫描电镜等手段研究了纳米Si O_2和MXene对粉煤灰水泥水化性能的影响。结果表明,单掺纳米Si O_2能够促进粉煤灰水泥早期水化,提高水化开始时的放热速率,并使粉煤灰水泥浆体更加密实;而单掺MXene、复掺纳米Si O_2和MXene对粉煤灰水泥后期水化的促进作用比较明显,能够促进水泥中期强度增长。

| Abstract: | The influence of nano-SiO2 and MXene addition on the hydration of fly ash cement was investigated by TGA, X-ray diffraction and SEM. The results revealed that hydration of fly ash cement is accelerated by nano-SiO2 at early age, improve the heat release rate at the begin of hydration and make fly ash cement paste more dense. However, MXene addition and binary combinations of nano-SiO2 and MXene have an notable acceleration on hydration of fly ash cement at later ages and can enhance the compressive strength of the cement. |
