STUDY ON PRACTICAL USE BY FULL-SCALE CONSTRUCTION FIELD TEST OF FLY ASH CONCRETE

Abstract

The purpose of this study is to evaluate the practical use of a concrete using high volume fly ash as a part of fine aggregate. In this study, the concrete was made at ready-mixed concrete plant, and the properties of concrete were measured at the process of pumping, placing and three years exposure of large specimen under marine environment. As the results from the full-scale construction field test, the following conclusions were obtained: The workability of the fly ash concrete are similar to that of normal concrete by considering the increase of viscosity with fly ash. The long-term strengths of this concrete are increased. The resistance of carbonation and the chloride ion penetration of this concrete are improved.
