摘要：

Nowadays the mechanical properties of epoxy resin used to paste CFRP strengthening the concrete structures, has a sharp drop in more than 60 degrees C. Four CFRP-strengthened concrete one-way slabs were studied in the fire, one using epoxy resin and the other three using inorganic adhesive (Magnesium Oxychloride Cement). The experimental results show that :(a) The fire resistance performance of CFRP-strengthened concrete slab by inorganic adhesive with 15mm thickness fire protection was better than the slab without fire protection; (b) Without considering the impact of burst, the fire resistance performance of CFRP-strengthened concrete slab by inorganic adhesive with 30mm fire protection was better than the slab with 15mm fire protection;(c)Under the same fire protection measures, the fire resistance performance of CFRP-strengthened concrete slab with inorganic adhesive was better than the concrete slab strengthened with CFRP by epoxy adhesive.
