Comparison of recycled aggregate treatment methods on the performance for recycled concrete

The effect of different aggregate treatment methods on the properties of both the recycled aggregate and the recycled concrete was studied. In this work, the compressive strength, dynamic elastic modulus, dry shrinkage rate, and chloride ion migration coefficient for five types of recycled concretes were investigated. Moreover, the Vickers hardness index and micro-morphology of new and old interfaces were analyzed. The results showed that...
