Abstract

Concrete is extensively used as one of the main construction materials in the maritime environment. At least 15% (by value) of these works includes concrete in various forms (sea walls and wave walls, concrete armour units, caissons, etc.). Despite the long history of capital investment in concrete maritime structures, it is generally recognised that there was a gap in structured guidance documents available with regard to the use of concrete in maritime structures. There remains a need to address unsolved challenges and to provide engineers with up-to-date guidance. KEY CHALLENGES FOR MARITIME CONCRETE The key challenges associated to the use of concrete in the maritime environment will be addressed are being addressed, in particular: - Designing for target performance of concrete elements. - Ensuring durable concrete material providing appropriate performance during the service life of the structure - Providing strength to concrete, without using conventional reinforcing steel - Designing with mass concrete - Mitigation of chloride-related corrosion of reinforcing steel - Delivering concrete resistant to attrition - Extent to which non-reinforced concrete armour units may be used to structurally respond to hydraulic loads - Appropriate testing of concrete for the maritime environment – in particular long term resistance to attrition, resilience to impacts, resistance to chloride attack, including laboratory testing and pilots - Repairing of maritime concrete structures
