ABSTRACT

In reinforced concrete the external environment most often affects the concrete and through it, the reinforcement (1,2). When reinforced concrete shows some signs of distress such as cracking, spalling or rust staining, it becomes necessary to carry out investigations to find out how serious it is, what has caused it and how it can be set right (3). This paper discusses one such investigation recently undertaken to study the corrosion damage in the structural members of a factory building housing ammonium chloride plant in the coastal area in North Madras. The scope of the work included attempts to evolve suitable remedial measures to make the building serviceable for a further period of 5 to 10 years.
