Prestressing 6, 253 cables wires

Steel wire and strand formed into cables is commonly used in the prestressing of concrete and in suspended or cable stayed structures such as bridges. In both cases it is sometimes necessary to splay the constituent wires or strands at the end anchorages in order to spread the load being transferred to the support material.

Concrete is a widely used structural material that is frequently reinforced with carhon steel reinforcing rods, post-tensioning cable or prestressing wires. The steel is necessary to maintain the strength of the structure, but it is subject to corrosion. The cracking associated with corrosion in concrete is a major concern in areas with marine environments and in areas which use deicing salts.
