Zusammenfassung:This study aims to improve workability of extremely stiff consistency concrete by using some kinds of admixtures and by arranging vibrating conditions (frequency, vibration period and acceleration). As the results of this study, it was found that flowability of the concrete under vibrating is improved by using fly ash that has spherical particles and by making the range of particle size distribution wider than that of cement. And it was made clear the relationship between workability of the concrete and the vibrating conditions.
