Abstract

Objectives: In this paper we have discussed about the case study of repair and rehabilitation work carried out for a G+3 residential apartments located very close to sea shore, Besant Nagar, Tamil Nadu, India. Methods/Analysis: The Repair strategy involved, removal of delaminated concrete cover, anti corrosive coating, polymer modified mortar, injection of epoxy grout for the repair of beam column junction and masonry crack, self sacrificial anode to prevent corrosion of reinforcement, micro concrete for slab and column, additional reinforcement with anti corrosive coating, glass fibre wrapping for column to increase ductility, and polymer modified mortar for repair of RCC and Masonry cracks. Findings: Though reinforced concrete structures are designed using the code provisions and standards, enough care should be taken during the construction process. During the service life of the building, proper maintenance and care should be taken to avoid corrosion of reinforcement and further environmental effects. Novelty/Improvement: A study of some modern concreting techniques and different types of special concrete used in the repair and rehabilitation process.
