Abstract:
The history of Japan’s high-performance concrete was summarized in this paper. The development of Japan’s high-performance concrete was started with the proposal for self-compacting concrete (SCC) by Okamura in 1986 and the completion of its proto type in 1988. Japan’s self-compacting concrete was inevitable high-performance/high-strength concrete due to its low water to cement/binder ratio. Because of its high cost due to high unit binder content, SCC has not been common in Japan with the share of around 0.1%. Following the situation, the authors have just developed an airenhanced SCC in which self-compactability can be enhanced by finer entrained air resulting in a unit binder content of less than 400 kg/m3 .
