Abstract: 
Research into concrete repair techniques, repair mortars and test practices is extensive. However, there is scant information on the repair of deteriorated concrete made with recycled aggregates. Investigations into the repair of such concrete are required. This paper reports the results of an experimental program aiming to assess the suitability of current repair methods for more modern, sustainable concretes such as those containing recycled aggregate. The experimental program consisted of three stages. The first stage was to deteriorate concrete specimens containing different types of recycled aggregates. The deterioration techniques included physical/chemical deterioration as well as failure due to overloading. In the second stage, the deteriorated concrete specimens containing different recycled aggregates have been repaired using traditional repair techniques. Finally, the mechanical properties of the repaired specimens as well as the bond between the substrate and the repair materials were assessed in the third stage. Test results proved that concretes made with recycled aggregates could be successfully repaired to form monolithic elements that act compositely and exhibit properties close to the original non-deteriorated specimen.
