Reinforced concrete structures have always been the first choice for the construction industry world over. This composite material has proved its robustness and versatility beyond doubts. However, these structures are subjected to constant deterioration due to effects of ageing, inadequate maintenance, severe environmental exposure, penetration of catalystic agencies such as moisture, gases like CO2 and oxygen, chloride ions, industrial pollutants, abuse (overused and misused), etc. This deterioration needs to be timely arrested before it leads to irreversible damage making it imperative to repair and upgrade (retrofit/strengthening) the current stock of deteriorated and deficient structures.
