concrete applying to high rising building. The main experimental variables were water/binder ratio 39.0, 41.0 and 43.0%, water content 160kg/㎥ and replacement ratio of fly-ash 0, 10, 20, 30(%) . According to the test results, the principle conclusions are summarized as follows.
1) The optimal mix design that was gained from the results of inside experimentation considering fluidity and durability under the status of fresh concrete is shown the water/binder 40% and the replacement ratio of fly-ash 25%.
2) The results of analyzing of hydration heating, it was shown that the cracking by hydration heating was reduced very much by using the P.E Film and the sheet on the surface.
