Throughout these comparisons, it is concluded that the most of the suggested insulating mixes acted efficiently to protect CFRP strengthened sections during fire. Temperature was significantly reduced at CFRP level -below the protective covers. It ranged between 100-120°C, for most of the mixes. Thus, enhancing significantly the fire resistance for CFRP retrofitted columns. Reduction in failure load capacity -due to fire exposure- was limited to 10-20% for most of the protected specimens. Even for the insulating mixes that resulted in lowest - post fire- residual strength, CFRP layer was highly damaged, but the reinforced concrete section was slightly affected, which still makes the damage repairable.
