Geocorail develops and commercializes an electrochemical process to produce a rock agglomerate from the marine environment, using materials present on site such as sand, gravel or shellfish debris. This " concrete", solid and extremely adhesive allows to repair or consolidate submerged or semi-submerged structures. Under the effect of a very low voltage electric current, mineral salts naturally dissolved in seawater (mainly calcium and magnesium) form compounds that precipitate around the frame and act as a natural cement.



Compare the colonization of concrete and Geocorail samples in-situ. Samples must be prefabricated in a chosen sediment, then installed in situ and monitored scientifically. The student, in collaboration with his supervisors, will put in place an experimental protocol, from the manufacturing to the follow-up of the colonization of the samples. The choice of targeted species, the immersion location, the sampling strategy and characterization techniques, etc., will be discussed during the first semester. Possible partnerships (Monaco Scientific Center, University of Marseille) are also possible if the project justifies it. The results of this study will be decisive for the future use of Geocorail as an alternative material dedicated to the restoration of coast (artificial reef, reinforcement or design of eco-designed work ...).
