Flexural performance of strengthened RC beams repaired with polymer resins
A series of 16 reinforced concrete beams was tested to evaluate the flexural performance of RC beams strengthened by epitaxy bonded plates after repair. The key parameters for this study were the repair materials, polymer, cementitious materials and strengthening materials, steel plates and carbon fiber sheets. The repaired specimens failed by a typical flexural mode with minor interfacial bond failure. The results show that the flexural performance of the strengthened beams is varied depending on the repaired material. Specimens with epoxy, polyester resins and latex modified cementitious mortars are effective for repairing the concrete beams, compared to specimens repaired with cement mortar. The flexural capacity of specimen strengthened by epoxy bonded steel plates or carbon fiber sheets after repair are less than those of strengthened specimens without repair. The interfacial behavior between the repair material and strengthening material was observed as the major influencing factor for the composite structures.
