초록

The columns and The belt wall of Tower Palace III were desined as 800kg/c $m^2$ ultra-high strength concrete. The concrete should meet or exceed the requirements of slump of 23cm, $\sigma$$_{18H}$ of 100kg/c $m^2$, $\sigma$$_{91th}$ of, 800kg/c $m^2$. The concrete mixings with 4 different domestic Silica fumes were investigated. Laboratory tests, the pilot productions of batcher plant and the full-scale mock up tests were performed. As results of site application, all test results are satisfied with the requirements of columns and belt wall.l.
