摘　　要：通过对缓粘结预应力钢绞线专用胶粘剂材料的成分以及从生产到施工阶段的胶粘剂材料的稠度扰动性进行了系统分析,同时开展了不同类型缓粘结胶粘剂在生产、运输、储存及施工阶段从缓粘结钢绞线取胶时产生扰动的恢复期进行试验研究,从稠度指标的变化入手进行评价、分析,得出了不同类型缓粘结胶粘剂的扰动恢复期及在不同环节下缓粘结胶粘剂稠度的扰动规律,对缓粘结预应力钢绞线产品的稠度控制指标的检测提供了合理、快速、有效的方法。This article provides a systematic analysis of the composition of special adhesive materials for retard-bonded prestressing steel strands and the consistency disturbance of adhesive materials from production to construc-tion stages,and conducts experimental research on the recovery period of disturbances generated by different types of retard-bonded adhesives extracting binders from retard-bonded steel strands at production,transportation,stor-age and construction stages.This paper evaluates and analyzes the changes of consistency indicators,and obtains the disturbance recovery period of different types of retard-bonded adhesives and the disturbance law of the consis-tency of retard-bonded adhesives at different links,which provides a reasonable,fast and effective method for de-tecting the consistency control indicators of retard-bonded prestressing steel strand products.
