摘要：
The influence of physical and chemical aging on the mechanical properties of two cold-curing epoxy adhesives, employed in reinforcing applications of civil engineering, was analyzed. The adhesives were subjected to 3-year natural exposure. The specimens only physically aged exhibit the highest values of static modulus and yield strength. The effects of chemical aging were found to be particularly severe on the filled adhesive. A de-aging treatment resulted in an incomplete recovery in modulus and strength. This effect was partially due to the crosslinking reactions taking place in the cold-cured adhesives.
