2、otype of self-compacting concrete was first completed in 1988 using materials alreadyon the market. The prototype performed satisfactorily with regard to drying and hardeningshrinkage, heat of hydration, denseness after

3、 hardening, and other properties. This concrete wasnamed “High Performance Concrete.” and was defined as follows at the three stages of concrete:(1) fresh: self-compactable(2) early age: avoidance of initial defects(3)

4、hardened: protection against external factorsAt almost the same time, “High Performance Concrete” was defined as a concrete with highdurability due to low water-cement ratio by Professor Aitcin. Since then, the term

5、highperformance concrete has been used around the world to refer to high durability concrete.Therefore, Okamura has changed the term for the proposed concrete to “Self-Compacting HighPerformance Concrete.”2. APPLIC

6、ATIONS OF SELF-COMPACTING CONCRETESince the development of the prototype of self-compacting concrete in 1988, the use of self-compacting concrete in actual structures has gradually increased. The main reasons for theem

7、ployment of self-compacting concrete can be summarized as follows:(1) to shorten construction period(2) to assure compaction in the structure:especially in confined zones where vibratingcompaction is difficult(3) to elim

8、inate noise due to vibration: effective especially at concrete products plantsThat means the current condition of self-compacting concrete is a “special concrete” rather than standard concrete. Currently, the percentag
