Experimental Analysis of Concrete Members Reinforced by Paste Method in the Fire

The fire resistance rating of concrete members coated with different thickness of fire-resistant coating was analyzed by experiment in the fire. Studies showed that the impact of CFRP and steel on the temperature field of the specimens was same, the fireproof effect of thick-layer fire-resistant coating for steel structure was obvious, the thickness of the fire-resistant coating and the fire performance are not proportional. It was identified that the best value of the thickness of fire-resistant coating is 40mm, and it provided the basis for fire protection design of reinforced concrete members after reinforcement.
