Influence of the Intrinsic Characteristics of Cementitious Materials on Biofouling in the Marine Environment

Coastal marine ecosystems provide essential benefits and services to humanity, but many are rapidly degrading. Human activities leading significant land take along coastlines major changes in ecosystems. Ecological engineering tools capable of promoting large-scale restoration coastal needed today the face intensifying climatic stress human activities. Concrete is one materials most commonly used construction infrastructure. Immersed seawater, concretes colonized by microorganisms macroorganisms. Surface colonization subsequent biofilm biofouling formation numerous advantages these organisms support critical ecological biogeochemical functions changing environment. The new challenge 21st century develop innovative that, addition their usual properties, improved bioreceptivity order enhance biodiversity. aim this study master clarify intrinsic parameters that influence (biocolonization) cementitious By coupling (culture-based methods) (image-analysis-based method wet-/dry-weight biomass measurement) quantification techniques, showed application a curing compound concrete surface reduced biocolonization whereas green formwork oil had opposite effect. This also found certain conditions (faceted patterned surface, rough surface) promote bacterial macroorganism materials. Among examined, roughness proved be factor promotes effectively. These results could taken up future recommendations enable engineers eco-design more eco-friendly infrastructure green-engineering projects.
