To study fundamental properties of so-called super-high-strength concrete, whose 28-day strength exceeds 60 N/mm^2, nine mix proportions of super-high-strength concrete were prepared respectively in full scale with a large-sized mixer in a ready-mixed concrete plant, transferred to author's laboratory about 20 minutes after the mixing, and subjected to tests of properties of fresh and hardened concrete. As a result, different properties of the super-high-strength concrete, including temperature change of simulation columns of the concrete, could be grasped. In particular the test results elucidated the face that, as one of the noticeable tendencies of the super-high-strength concrete, its long-term strength increase only at a small increasing rate with time lapse, thereby involving the necessity for elaborate placing, compaction and initial curing works as required for other types of concrete which have general strength.
