The prestressed tendon is a steel stranded wire or a steeltendon or a single reinforcing steel bar.
所述的预应力筋是钢绞线或钢丝束或单根钢筋。

As a result, replacing steel bar with CFRP in reinforcement concrete may effectively overcome corrosion of steeltendon and increase structural durability.
因此，在混凝土结构中用CF RP筋代替钢筋，可以有效的克服钢筋的腐蚀问题，提高结构的耐久性。

More recently, a effective idea is the way to replacing steeltendon or prestressing strands with the fibre reinforced plastics or polymer in reinforcement concrete.
