This study is to choose the optimal mixture and to analyze the sensibility properties of High strength concrete and mass concrete to apply the high rising building. The main experimental variables were water/binder ratio 31%, 33%, 35% and 37%, replacement ratio of fly ash 5%, 10% and 15%, in the high strength concrete and water/binder ratio 39%, 41% and 43%, replacement ratio of fly ash 10%, 20% and 30%, in the mass concrete.According to the test results, the principal conclusions are summarized as follows.1) The slump(or slump flow) and air content of fresh concrete were found to be the highest in the elapsed time 30 minutes.2) The optimal mixture conditions are W/B 40%, FA 25% in the mass concrete and W/B 33.4%, FA 15% in the high strength concrete.3) The ranges of sensibility are satisfied in the moisture content ±1% and S/a ±2%
