Abstract

Abstract

The effects of curing time,binder strength,slot size and surface treatment on the bond strength were further studied. Pullout tests of 36 specimens were conducted to study the bond strength of the CFRP rods,and then four different bond materials were compared. During the experiment process,the failure modes,the slip between the CFRP and concrete and the cracking type were studied in detail. From the experimental study,it could be found that the influences on bond strength of binder strength,slot size and carbon fiber reinforced surface treatment technology were significant,but the curing time was small or neglected. The bond properties of epoxy mortar which made by quartz sand was excellent,which would be worth while popularizing.
