| 摘要: |
| 用溶胶 凝胶膨胀法研究了骨料碱活性．试验结果表明，用碱与骨料直接反应的溶胶 凝胶膨胀实验方法能比较灵敏地区分出骨料的不同碱活性，可作为一种新的化学法快速地检测骨料的碱活性．研究表明，花岗岩在不同地质构造应力下产生的石英变形及不同地层风化条件下产生的矿物蚀变，有可能造成其与碱的不同反应能力． |

| Abstract: |
| Sol Gel expansion method was used for the first time to study reaction of granite aggregates with alkali. The results show that Sol Gel expansion method is sensitive to distinguish different reactivity of aggregates by direct reaction between alkali and aggregates. So this method will be developed into a new chemical test. Depending on deformation of quartz caused by different geologic stress and erosion of minerals caused in different efflorescent condition, granite could be different in reactivity with alkali. |
