Abstract
The workability of high strength concrete with specified design strength of 150MPa and its strength development in RC columns were investigated, and the following results were obtained. (1) Strength in structure of columns placed in both summer and winter were more than 170MPa (2) The strength at the outer part in the columns placed in winter was similar to that of the center of the same columns. (3) The strength development of core specimens of the upper part of the RC column was similar to that of the lower part of the same column, and no segregation of the course aggregate was seen.
