A comparison of durability and recruitment for reef mimics constructed from marine concrete and CaCO₃-enriched concrete

Coastal landscapes continue to be altered on a global scale by man-made infrastructure. Coastal and marine infrastructure, such as seawalls, breakwaters, have replaced natural intertidal, subtidal, and benthic habitats along many coastlines. Coastal infrastructure has a multitude of impacts on biodiversity and ecosystem functioning. The habitat provided by man-made coastal infrastructure typically supports ecological communities that are characterized by greater abundances of invasive species and lower overall biodiversity. New design approaches have emerged with the aim of mitigating the impacts of man-made coastal infrastructure, but few studies have investigated the role of CaCO₃ as a concrete additive in increasing biodiversity, species recruitment, material strength and durability, and ion leaching. Textured reef mimics in both standard marine concrete and CaCO₃-enriched concrete were studied constructed and deployed along the coast in Dorchester Bay, Massachusetts.
