But these structures are increasingly being deteriorated, mainly due to the chloride-induced corrosion of the embedded bars. Consequently, hundreds of million dollars are spent for repair and rehabilitation every year. In marine structures, piles are often subjected to the most severe corrosion due to the permanent wet and dry cycles. Precast prestressed concrete piles have been used for more than 50 years in marine applications. As a main conclusion, the combination of dense, high-quality concrete and permanent axial compressive stress results in minimal cracking, very low chloride ion diffusion and high electrical resistivity. Both site investigation and laboratory tests show that PSPC piles are appropriately durable with a high service life under severe conditions.
