CORROSION DE STRUCTURES EN BETON ARME ET PRECONTRAINT A L'EAU DE MER

THE AIM OF THE RESEARCH IS TO STUDY THE BEHAVIOUR OF REINFORCED AND PRESTRESSED STRUCTURES UNDER THE ACTION OF NATURAL MARINE ENVIRONMENT. 40 BEAMS WERE HALF-IMMERSED IN THE MEDITERRANEAN SEA TOGETHER WITH CONTROL SPECIMENS WHICH WERE TOTALLY IMMERSED. REGULAR OBSERVATIONS ENABLED THE EVOLUTION IN THE STRUCTURES TO BE FOLLOWED UP DURING 10 YEARS OF EXPOSURE.
