| Abstract: | In the construction of the National Gymnasium,based on the characteristics of the shaped-steel concrete columns,the recipes of the self-flowing concrete of C40 and C50 are developed,and the pressure of concrete against to the form panels for the super high-rise columns(14 m high) is detected.The self-flowing concrete poured and dropped into the forms,no vibrating.The finished columns are compacted and smooth. |
