- Abstract:
- The interfacial transition zone is a weak link of concrete structure, and a main reason of concrete cracks, so it is the most important way to increase interfacial bond strength by improving the structure of the concrete interface. This paper puts forward two methods, vibratory mixng method and secondary mixing method, to strengthen concrete interfacial bond strength. The mechanisms and experimental devices of vibratory mixing method and secondary mixing method are developed and tested. The results show that the concrete strength can be increased by vibratory mixing method, and the interface structure is changed and improved by secondary mixing technology. 4 tabs, 6 figs, 9 refs.
