Floating breakwater pontoon pilot cast with carbon textile reinforcement-based ultra high durability concrete: Materials development and testing, and implementation in the North Atlantic (Irelands west coast)

A floating unit with three pontoons made of epoxy-coated carbon textile reinforced, ultra-high durability concrete (ECF UHDC), mineral impregnated fibre-reinforced UHDC (MCF UHDC) and, as references, steel-reinforced concretes has been designed and installed in the Northern Atlantic. While marine structures steel reinforcement require large cover depths, which cause problems size, cost, environmental friendliness short service life, reinforced (TRC) cannot suffer from chloride-induced corrosion a metal reinforcement. In EU H2020 project “ReSHEALience” (rethinking coastal defence green-energy infrastructures through enhanced-durability highperformance cement-based materials), TRCs have modified functional admixtures consortium partners. self-healing promoter alumina nano-fibers have, among others, implemented to boost high-performance towards UHDCs. Resulting composite variants applied full-scale that launched harbor Galway at Irish West Coast June 2020. Such body is representation breakwaters reduce wave impacts coast. Besides, TRC-based can be strengthening repair layer on enhance their life general.
