cracking, which very likely initiated the failure of the strands. Consequently, the failure was not due to the lack of quality or deterioration of the prestressing steel, and the failure roots were the long-term constructive insufficiencies that propitiate the absence of protective barriers and the presence of an aggressive media inside the protection

sheaths of the strands. Acknowledgements
