Creep tests were performed at constant high temperatures for super high strength concrete.Then,for some of the specimens, the temperatures were maintained and compression tests were performed. Results of these tests revealed following.1)The effect of water-binder ratio on creep strain is minimal. 2)Creep strain of super high strength concrete is higher than normal concrete- at the same stress levels. 3)Increased creep strain is dependent upon elevated temperature but these increases are not uniform. 4)Creep strain is proportional to stress in the range 100℃ to 400℃. 5)Results of these tests can be simply formularized by Anderberg' s methoP.6)Increased strength and stiffness are observed for the sepecimens after creep tests.
