    • PURPOSE: A concrete composition for concrete filled tube (CFT) with improved fire resisting capacity is provided to improve mobility at a solid state and workability, rigidity and fire resisting capacity after being solid by comprising a nylon fiber, a long steel fiber, and a short steel fiber. CONSTITUTION: A concrete composition for concrete filled tube (CFT) with improved fire resisting capacity comprises: 150-200 kg of water; 800-950 kg of binding material; 400-500 kg of fine aggregate; 700-900 kg of coares aggregate; 6-20kg of polycarboxylic acid based water reducing agent; 5-40 kg steel fiber; and 1-2 kg of nylon fiber per unit volume 1m^3. A water to binder ratio (W/B) of the concrete composition for CFT is 17-18%, and the fine aggregate percentage (S/a) is 35-40%. The steel fiber comprises a long steel fiber which has a length less than 55 mm and over 50 mm, a short steel fiber which has a length less than 15 mm and over 5 mm. The long steel fiber is used along with the short steel fiber as a ratio of 1:1.
