Nowadays, with high-storied and large-sized of structures, high-strength concrete is applied to the various kinds of concrete structure. Among of them, for reduction of completion time, high-strength concrete is applied to the high-storied tower, building which is constructed continuously by the slip-form method and it is expected to be on the increase. In this case, it is very important to grasp development of early-strength to apply the slip-form method. But the strength data prior 1 day is rare. Therefore, to apply slip-form method in field, this study aim is to present basic data for development of early-strength of high-strength concrete, through examining development of strength by different curing temperature, replacement of fly-ash.
