| Abstract: | Expansive concrete with good workability and high strength was prepared in this paper. The mechanical properties of expansive concrete filled steel tube (CFST) were measured. The expansion model of concrete core was analyzed. The results show that, when the expansive agent is added properly, the mechanical properties of expansive CFST is better, and its limit bearing capacity is 8% more than that of common CFST. |
| Keywords: | expansion \ concrete filled steel tube \ mechanical property \ expansion model |
