| 摘 要： | 研究了在不同蒸养温度下不同掺量粉煤灰对水泥基材料干燥收缩以及孔结构的影响.结果表明:在较高养护温度下,水泥基材料收缩以及孔隙率随着蒸养温度的升高与粉煤灰掺量的增加均呈下降的趋势;纯水泥体系的水泥基材料则呈相反的趋势.

| Abstract: | The drying shrinkage and pore structure of cement-based material were investigated in different stream-curing temperature and different dosages of fly ash.The results showed that the drying shrinkage and porosity of cement-based material were tended to be reduced in higher temperature or with more dosages of fly ash in the condition of high stream-curing temperature;and they took the opposite tendency without fly ash. |

| Keywords: | stream-curing temperature fly ash drying shrinkage pore structure |
