SELF-COMPACTING CONCRETE Masahiro OUCHI 1 SUMMARY Self-compacting concrete was first developed 1988 in order to achieve durable concrete structures. Since then‚ various investigations have been carried out and the concrete has been used in practical structures in Japan‚ mainly by large construction companies. Investigations for establishing a rational mix-design method and self-compactability testing methods have been carried out to make the concrete the standard one. Keywords: self-compacting
