The objective of this paper is to investigate the effects of fine aggregate grading and granule volume in concrete on the behavior of fresh super workable-concrete with viscosity agent, for the full-sandwich structure. The granule volume was adjusted by blast furnace slag powder as fine aggregate. The behavior of fresh concrete was studied by slump-flow test evaluating defomablity and by V-type funnel test evaluating flowability through small openings, which is one of the most important properties of self-compactable concrete. It is experimentally verified that these properties are not remarkably changed by fine aggregate of different kinds or granule volume, but the self-compactability of concrete is improved by using of blast furnace slag powder as granule.
