| 摘 要： | 在混凝土结构的修补和加固工程中 ,新老混凝土的粘结性能是最为关键的问题。而新老混凝土粘结面的抗剪切性能在两部分混凝土共同受力中起着极为重要的作用。采用 3年龄期的老混凝土 ,通过比较 ,浇制了一批Z形新老混凝土粘结试件和整体混凝土伴随试件。通过剪切试验研究 ,得出了不同界面剂对新老混凝土粘结剪切性能的影响规律 ,并进行了双因素方差分析。

| Abstract: | The property of bond between new and old concrete is the critical problem in the repair and reinforcement projects of concrete structure. The shear property of the interface between the new and old concrete plays a crucial role in common work of two part concrete. By comparison this paper takes three year old concrete to cast a series of Z shape new old concrete bonding specimens and integral concrete compared specimens. By shear testing investigation, the influencing laws of different interfacial agents on new old concrete bonding shear property are obtained and the double factors variance analysis is presented. |
