Durable and Environmental design of Monitored COncrete structures in Marine environment – DEMCOM

This interdisciplinary project deals with Durability Life Cycle Assessment (LCA) and Life Cycle Cost (LCC) of Reinforced Concrete (RC) structures under marine environment like wharf, bridges, floating wind turbines etc… The objective is to develop a new eco design method to maximize service life and minimize environmental impacts and costs of RC structures submitted to chloride ingress. In the context of changes of structure uses, climatic environment and service life prolongation, the Non Destructive Evaluation (NDE) during inspection coupled with durability model and, LCA and LCC decision diagram can bring very useful tools for structure managers. These stakes require NDE results to be directly integrated in durability models to improve the health diagnosis and thus the service life prognostic by minimizing environmental impacts and costs. Sensitivity Analysis will be developed and used to determine which action levers have to be modified to this aim.
