In this paper, effects of maximum aggregate size, binder type and content, and water-binder ratio on the compressive strength development and workability of ultra-high strength concrete are investig ated experimentally. Selected test variables are 3 levels(13, 19, 25mm) of max. aggregate size, 5 levels of water-binder ratio(22, 25, 28, 32, 36%), and several conbinations of fly ash and silica fume. As the results of this study, the 28-day compressive strength is decreased with increasing of max. aggregate size, however, the effect of max. aggregate size on the 28-day compressive strength is not great in the range of 13-25mm. The effect of max. aggregate size on the workability is decreased with increasing binder content. In the case of 30% fly ash plus 5% silica fume replacement, the strength is significantly decreased compared to control mix.
