| Abstract: | 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. |

| Keywords: | fly-ash alunite anhydrite ettringite expansion |
