Abstract:A 17-story reinforced concrete structure with prestressed concrete floor slab, clad with an architecturally pleasing white cement and calcined stone aggregate, exhibited signs of deterioration after 30 years exposure to central London environment. The investigation was instigated after a piece of concrete spalled from a high level and crashed down. After the investigation, when the cause of the deterioration was established, recommendations were made to the client and specifications for repair were made. After the repair specialist was selected the author supervised the repair ensuring that the specifications were strictly followed. The paper describes the investigations and the rehabilitation of the structure.
