DURABILITY ASSESSMENT OF CONCRETE

This paper describes the durability assessment and performance monitoring of the concrete in the Tees Barrage in England. The barrage was made from granulated blastfurnace slag cement, with specified durability of 120 years. The Building Research Establishment was commissioned to monitor the performance of the concrete. The assessment aimed to: (1) identify potential deterioration processes in the structure's concrete; (2) estimate the concrete's performance in service in relation to its original design intent; (3) establish whether the expected life of the concrete structures is likely to be achieved; (4) provide guidance on maintaining the concrete structures; and (5) identify preventive maintenance works, which would help to minimise maintenance costs for the concrete structures. The assessment combined a desk study of the mix design and materials used with visual examination, testing of material samples, and electrochemical monitoring. The monitoring programme obtained data about curing temperatures, compressive strength, oxygen permeability, and chloride ingress. The data collected during the first 18 months of monitoring indicated that the concrete in the Tees Barrage largely met its specified requirements for low permeability, resistance to chloride ingress, and longer-term strength development.
