A thermodynamically consistent gradient theory for recycled aggregate concretes is proposed.
- class="label">•
This constitutive model depends on the confinement pressure and the recycled aggregate contents.

The occurrence of localized failure is studied by means of the acoustic tensor.
- class="label">•
The performance of the acoustic tensor is analyzed taking into account different recycled aggregate contents.
