|
|
摘要: |
通过测试Ca(OH)2含量、化学结合水量和水化放热量,探讨了纳米SiO2对硅酸盐水泥水化特性的影响.结果表明:纳米SiO2的掺入降低了水泥水化生成物Ca(OH)2含量,增加了水泥水化的化学结合水量及水化放热量. |

Effect of Nano-SiO2 on Hydration Character of Portland Cement |
LU Zhong-yuan XU Xun
|
Abstract: |
The effect of nano-silica powder on the hydration process of Portland cement was investigated by the studies of Ca(OH)_2 content,chemically-combined water content and heat of hydration.The results show that the presence of nano-silica powder decreases Ca(OH)_2 content,but increases chemically-combined water content and heat of hydration. |
Key words: nano-SiO_2,silica fume,portland cement,hydration |
