R EHABILITATION PROCEDURE

F

irst, as shown in Fig. 7, the per-failed specimens were mechanically ground to a satisfactory smoothness using appropriate grinding commercial sheets. After that, an air compressor was used to clean the beams, preventing dust from settling on the specimens. To produce the adhesive material for the CFRP installation, KUT BOND Epoxy was mixed using a laboratory spatula. Figs. 8 and 9 demonstrate how these sheets were placed and established using an appropriate roller to prevent trapped air.
