| Abstract: | By test to illuminate the special coating for slow cohesion PC stranded wire. The break resistance strength averages 39.1MPa after solidification, its compression strength averages 104.4MPa, which can satisfy the requirements of prestress concrete structure at present. To introduce the production process of slow cohesion PC stranded wire and the determination results of μ and k value of the stranded wire in tensile working of prestress muscle. It is pointed out that the slow cohesion PC stranded wire can meet the needs of prestress engineering, it is development orientation of prestress muscle. |
