摘要：

By bond-anchorage property tests at 20 degrees C similar to 500 degrees C, the distribution of shear stress between carbon fiber sheets and concrete at all levels of loading and anchorage lengths were measured, which means the bond lengths during CFRP sheets are pulled off at the same time when the concrete is torn and stripped were gotten. The failure modes were obtained. In addition, the failure loads were measured, and the calculated formulas of anchorage lengths were identified by fitting at high temperature. It can be seen that the anchorage lengths of carbon fiber sheets increase with increasing temperature at 20 degrees C similar to 100 degrees C, the anchorage lengths of carbon fiber sheets decrease with increasing temperature at 100 degrees C similar to 500 degrees C. Tests prove that AASCM has favorable high-temperature resistant and bond anchorage properties.
