To evaluate the property and degradation characteristics of concrete prepared with aggregate contained montmorillonite,concretes were prepared with aggregates contained montmorillonite,and then concrete slump loss,compressive strength,electric flux,the resistance to carbonization,freezing-thawing and sulfate attack were evaluated.The results show that montmorillonite appearance alters concrete slump loss and compressive strength.But montmorillonite increases electric flux and compactness.The carbonization,freezingthawing and sulfate attack results indicate that montmorillonite enhances carbonization depth,increases mass loss after 300 cycle freezing-thawing,as well as mass loss after sulfate attack.Overall,it is adverse to the concrete resistance to the carbonization,freezing-thawing and sulfate attack.
