| 摘 要： | 采用拔出试验,对芯柱自密实混凝土和普通混凝土与钢筋握裹强度进行了对比试验研究.结果表明:不管是光圆钢筋还是带肋钢筋,芯柱自密实混凝土与钢筋握裹强度均高于普通混凝土,并对其机理进行了初步探讨,为自密实混凝土应用于芯柱提供了依据.

| Abstract: | In this study,the bond strength between concrete and steel bar are studied between the core column self-compacting concrete and ordinary concrete by pull-out test,The results show that,whether smooth steel bars or ribbed steel bars,bond strength of core column self-compacting concrete and steel bars are higher than normal concrete,and its mechanism is conducted a preliminary study,the results provide the basis for the self-compacting concrete application in core column. |
