The study examined basic characteristics of fresh concrete and dynamic characteristics of hardening concrete followed by changes of mixing rate in fluidity-keeping agent as admixture to improve fluidity-keeping performance of high-performance concrete. There sults were as follows. Slump flow satisfied the scope of target in all mix proportions by design of mix proportion and its fluidity-keeping performance was better as the mixing rate of its keeping agent was increased irrespective of W /B, Air amount satisfied the scope of target in all mix proportions by design of mix proportion and all of the air amount followed by the diurnal variations irrespective of W IB was decreased. The setting time followed by each change of mixing rate in keeping agent was more delayed as W IB was higher and as the mixing rate of keeping agent was more increased. The setting time followed by change of curing temperature was more promoted as curing temperature was higher and was more decreased as the mixing rate of keeping agent was more increased. In changes of curing temperature, the early strength was more increased as curing temperature was higher and the early strength was similar irrespective of change of curing temperature in long-term age.
