Abstract

Highly fluidized concrete is now coming to a practical stage of use and its applicability has been verified through various kinds of concrete constructions. In this paper, the authors proposed the slump-flow value and V-shaped funnel value that should be required for each structure based on data obtained from actual construction works. And also we proposed the procedure for selecting mix proportion of the concrete with viscosity modifying agent of welan gum from the results of experiments both on fresh and hardened properties of the concrete. The procedure were used successfully in actual construction works.
