Influence of Fine Aggregate Grading on the Behavior of Fresh Super-Workable Concrete with Viscosity Agent

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.
