Abstract

Corrosion of reinforcement is one of the devastating form of deterioration that any concrete structure has to withstand. One of the leading causes of corrosion often overlooked is the process of carbonation in the concrete. Carbonation is the reaction between calcium hydroxide and atmospheric carbon dioxide. This reaction reduces the pH concrete which causes the corrosion of the reinforcement in RCC structural elements. This paper deals with a case study of repair of columns damaged by carbonation induced corrosion.  This paper incorporates use of Indian Standard 15988-2013for retrofitting of these damaged column. The case study has been taken from one of the building in Navi Mumbai, India which was undergoing distress due to cracks in two external columns. Servers cracks were found of the columns and after evaluation of strength of concrete, it has been decided to carryout retrofitting of these two columns using IS 15988-2013. After strengthening the columns using jacketing method, the building appears to have stabilized and no further crack propagation has been observed in the building.
