粉煤灰掺量对自密实混凝土与钢筋粘结性能影响的试验研究
Experiment study of fly ash content influence on bond performance between reinforcement and self-compacting concrete
摘要
Abstract
Due to fly ash content influence, the bond characteristics between reinforcement and self -compacting concrete were analyzed experimentally. The tests were conducted on eighteen specimens and all specmens were pull out by electro hydraulic servo device. The fly content influence on average and local bond performance were analyzed. Influence laws of average and local bond performance including bond ultimate bond strength, each bond stiffness and degradation rate and local bond performance including tress unven coefficient and bond stress distributions along anchorage length were obtained. The results show fly content have influence on bond stiffness of micro slip stage, bond stiffness of slip stage and bond stress unven coefficient while have little influence on other bond performance.关键词
