摘要
试验研究选择了上补、侧补、斜上补、斜下补和下补 5种界面方位 ,3个月和 3年新老混凝土龄期差 ,多种新老混凝土界面处理方法和界面剂 ,首次提出并系统地探讨了新老混凝土修补界面方位对粘结强度的影响 ,并分析了影响机理。
In the first instance the influence of the position of the repaired interface on the bonding strength of new to old concrete was proposed and systematic researched.Five positions of the repaired interface,namely upper repaired,down repaired,upper inclined repaired,down inclined repaired and side repaired were included in this experimental research.Two kinds of new to old concrete age differences(three months and three years) and various methods of interface treatment and primers were involved.
