New building materials for repair of concrete structures have to be investigated by qualification tests to estimate their long-term behaviour. This report deals with such tests for polymer cement concrete (PCC) composite repair systems hardening under dynamic loading followed by thermal cycling tests on the cured composite specimens. Test results showed that shrinkage of PCC and/or thermal stressing of the composite system especially in the bonding interface are decisive for durability of PCC layers on concrete, whereas dynamic loading of the fresh composite system seems to be of minor consequence.
