摘要
针对明矾石较高含碱量而引起的碱集料反应问题,拟采用粉煤灰代替明矾石与硬石膏共同作用的方法来生成具有膨胀作用的钙矾石,试验结果表明,试件具有较好的膨胀率及抗压强度。
Alunite with too much alkali will produce alkaline -aggregate reaction. In the research, alunite is replaced by fly - ash to react with anhydrite to generate ettringite, which is expandable. The result shows that the operation is effective and the testing sample has good expansion rate and resistance.
