摘要：

In order to investigate fire protection performance of recycled concrete, thermal conductivity and specific heat of recycled concrete prepared from different replacement ratio of recycled coarse aggregate to natural aggregate were calculated. Results show that recycled concrete has better thermal conductivity than traditional concrete, which was proved to be reliable by experiment results. Specific heat of recycled concrete was suggested. Farther, the warming of section steel in steel reinforced recycled concrete columns and steel reinforced concrete columns was studied using EUROCODE 3. Results indicate the delay time of recycled concrete is about twice that of traditional concrete. Fire protection performance of recycled concrete is excellent and helps to improve the fire resistant capacity of structure.
