摘要
考虑再生混凝土的强度等级,再生骨料替代率以及膨胀剂的掺量百分比等因素,制作了9根方钢管再生混凝短柱进行推出试验,得到并分析了各试件的荷载-滑移曲线关系,总结出了各种因素对方钢管再生混凝土黏结滑移性能影响规律,对工程应用有一定的借鉴意义。
The parameters concerned were strength grade of the recycled concrete,recycled coarse aggregate replacement rate and expan- sive agent dosage,nine recycled aggregate concrete-filled square steel tubes specimens were designed for the push-out tests.The load-slip curves are obtained and analyzed, factors referred above in this test are deeply investigated, which may be reference for engineering practice.
