STUDY ON ADHESIVE MATERIALS FOR RETARD-BONDED PRESTRESSING STRAND
-
摘要: 依据缓粘结预应力钢筋的技术特点,开发出符合技术要求的专用缓凝胶粘剂材料,测试了其物理、化学性能,分析了缓凝胶粘剂材料的特有属性,结果表明,缓凝胶粘剂具有优良的性能指标。同时,结合缓凝胶粘剂的性能特点,对其固化过程和抗扰性能进行分析,明确了温度对固化时间和填料对抗扰性能的影响。Abstract: According to the technical characters of retard-bonded prestressing strand,it was developed the special adhesive materials conforming to the requirements of retard-bonded prestressed concrete technique,then further tested the physical and chemical properties,analyzed the unique attributes of adhesive.The result indicates that the adhesive has good performance index.At the same time,it was analyzed the solidifying process and anti-confusion capacity by the performance characteristics of the retard-cohesive adhesive,and defined the effect of temperature on solidifying time and that of filling on anti-confusion capacity.
