| The harsh and highly corrosive environment in the Eastern Province of Saudi Arabia results in corrosion of reinforcement and subsequent cracking and spalling of concrete. The deterioration in primary load carrying members poses a potential threat to overall structural integrity. When a patch repair of deteriorated column is carried out, its effectiveness in restoring the original stress pattern is not known. Repair material properties and the effect of carrying out repairs in columns in loaded or unloaded state is believed to play an important role in magnitude of stresses developed in repair layer and concrete core.; An experimental investigation was carried out to assess the behavior and performance of a patch repair in an axially loaded column.; For performing effective patch repair in deteriorated columns, it is highly recommended to relieve the structure from loads, at least partially, and then proceed for patch repair.
