Valorization of dredged sediment or raw earth (clays) in ecological Concretes (VALOSED)
- In the field of civil engineering, the increase in demand for granular materials combined with environmental constraints for the opening of new quarries requires better management of natural resources. In this project, the valorization of waste such as dredged sediments could constitute an alternative solution to save the resource. in particular valorization of fine fraction (clays) is proposed. Analysis of mechanical properties and durability of the formulated concretes are studied and models to mitigate the problems of variability of the sediments are proposed.
- This project also constitutes a novelty related to the nature of the complex studied mixtures (clay-cement-electrolyte...) and try to bring answers to the current scientific barriers in bio-sourced concretes area. Physical-chemical tools will be used to characterize sediments. Alkali-activation tests of clayey sediments will be carried out in order to indicate the possibility of using clayey sediments as a substitute for cement.
