RESIN COATED PC STEEL STRANDED WIRE HAVING HIGH YIELD POINT RATIO AND LOW RELAXATION PROPERTY AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a resin coated PC (prestressed concrete) steel stranded wire having a high yield point ratio and low relaxation properties and to provide a method for producing the same.;SOLUTION: The resin coated PC steel stranded wire having a high yield point ratio and low relaxation properties is a resin coated PC steel stranded wire obtained by stranding a plurality of steel wires to give a stranded wire and coating the external surface of the stranded wire with a resin and has ≥90% yield point ratio of the stranded wire coated with the resin and ≤2.5% relaxation value of 1,000 hours. The method for producing the resin coated PC steel stranded wire is provided.;COPYRIGHT: (C)2006,JPO&NCIPI
