Structural Concrete Repair against mechanical and thermal loads

The study presents applications of different material systems for repair that have evolved in recent years for application to structural concrete elements as a means of rehabilitation or retrofit. Both fibre reinforced polymer (FRP) of glass, or carbon in the form of a laminate or wrap with epoxy binding and fibre reinforced concrete with chopped short wire fibres that are mixed into a concrete matrix, even with a self-compacting concrete consistency at the time of casting as an alternate form of a repair system is discussed. Experimental results and analytical/numerical procedures that have been developed to predict the capacity of the variously (strengthened) reinforced structural elements is presented to illustrate the merit of different approaches. A model to predict thermos-mechanical damage is briefly discussed. Possible repair and protection against thermal damage is also briefly discussed.
