Abstract: 
Accidental loads—for example blast and shock waves caused by detonations or more commonly an earthquake or a vehicle impact—lead to a localized damage in Reinforced Concrete (RC) structures. Both the damage assessment as well as the repair techniques of concrete is an important topic with respect to the durable use of infrastructure. Following the damage assessment it is usually necessary to repair the damaged areas. Therefore fundamental investigations concerning the use of different repair techniques have been carried out with respect to damage resulting from an accidental action. This contribution studies different repair and grouting techniques that focus on some example repairs of cracks, concrete microstructure and weakened bond strength between the reinforcing bars and concrete in the surrounding damage zone. Furthermore, this contribution includes application oriented experimental investigations concerning the possible repair of severely blast damaged reinforced concrete elements by grouting and injection.
