STUDY ON PUMPABIRITY AND CORROSIVITY OF HIGH STRENGTH/HIGH FLUIDITY CONCRETE USING ECO CEMENT

Abstract

Applicability of high-strength/high-fluidity concrete using eco cement to environment-conscious CFT was examined. As a result, the following conclusions were obtained. (1) Within W/C=28% or more, high-strength/high-fluidity concrete using eco cement can be placed with a usual concrete pump. (2) In the comparison with W/C=35%, high-strength/high-fluidity concrete using eco cement had a pumpability almost equal to high-strength/high-fluidity concrete using ordinarily portland cement. (3) The corrosivity of high-strength/high-fluidity concrete using eco cement with W/C=35% was smaller than that of concrete using ordinarily portland cement with W/C=50%.
