| 摘 要： | 进行15个石材复合砂浆试件粘结性能双剪推出试验,研究砂浆种类、砂浆强度和抗剪连接件等参数对砂浆与花岗岩石材界面粘结强度的影响.试验研究表明,自配改性砂浆比商品聚合物砂浆具有更好的界面粘结性能;界面植入U型抗剪连接件,能较显著提高砂浆与石材的界面粘结抗剪强度;采用自配改性砂浆和商品聚合物砂浆,其界面抗剪强度均可满足石材受弯构件加固界面抗剪需求.

| Abstract: | Double shear push-out experiments of 15 specimens are carried out,to investigate the influence of various factors on the interface bonding strength between mortar and stone,including the kind and strength of mortar,and shear connector.The experimental results show that the interface bonding performance of the specimens with self-made modified mortar is better than the one with commercial polymer mortar.The embedded U-shape shear connector can significantly improve the interface bonding strength between mort... |
