| Abstract: | The effect of the content of expansive additive and steel tube wall thickness on the mechanical properties of expansive concrete filled square steel tube were studied.The experimental results show that the limit loading capacity of expansive concrete filled square steel tube is increased by 15% more than that of common concrete filled square steel tube by adding some content of expansive additive.The greater the steel tube wall thickness,the higher the limit loading capacity of expansive concrete filled square steel tube is. |

| Keywords: | expansive concrete expansive concrete filled square steel tube axial compression experiment |
