Bioreceptive concrete for marine infrastructure with eco-friendly binders: a comprehensive review

Le résumé fourni par la source

Marine infrastructure and the ‘greying’ of coastlines are predicted to increase as it is necessary for transport, tourism, fishing, and protection. Concrete is often the main component used in marine infrastructure. There has been significant research into improving the performance of concrete within the marine environment. Recently, the use of ‘eco-friendly’ materials to replace Portland cement within marine concrete has been investigated to determine if they impact the durability of marine concrete. The impact on the bioreceptivity of the materials’ inclusion in concrete has also been reviewed, as traditional concrete is not compatible with the marine environment and does not replicate natural marine communities. However, there are very few papers reviewing both the mechanical and ecological characteristics of marine concrete that partially replaces or fully replaces Portland cement with eco-friendly alternatives. This review summarises research from the engineering community to improve the mechanical characteristics of marine concrete, research from the ecological community to improve the bioreceptivity of marine concrete, and the few papers that have researched both. While there have been other reviews researching either the mechanical characteristics or the bioreceptivity of marine concrete, there has not been a review looking at both. This review aims to fill this gap and increase the possibility of interdisciplinary work between engineers and ecologists in future research. Suggestions for future work aiming to both improve the durability and the bioreceptivity of marine concrete are provided.
