REPAIRS TO REINFORCED CONCRETE.

Reinforced-concrete structures are inherently durable and normally give long maintenance-free service. However, problems are not totally unknown and concrete in such structures occasionally cracks and subsequently spalls as a result of corrosion of the reinforcing steel. This damage is usually a consequence of design or construction inadequacies and can be alarming to those responsible for the structure. This article discusses various agents of the title subject, including reinforcement protection, investigation aims and techniques, analysis of heat results, structural implications of deteriorated concrete, repair techniques and materials.
