The traditional P-wave ultrasonic measurement has been used for the condition assessment of general reinforced concrete structures for a long time, but the effects of prestressing applied to concrete structures such as long-span buildings and bridges on ultrasonic pulse velocity have not been studied clearly. Therefore, this study analyzed the statistical distribution of P-wave ultrasonic

Advantages of offshore concrete structures | The …

A common failure mode of prestressed concrete structures is corrosion of the steel cables used to tension them. The steel is usually treated with materials like wax for corrosion resistance, but if water can work its way to the steel, the tensioners can corrode and the structure can fail.
