The purpose of this study is to develop super flowing concrete (SF concrete) which can be placed uniformly and compacted densely without any mechanical vibrator. This SF concrete is produced by using superplasticizer to provide high fluidity and cellulose viscous agent to increase resistance against material segregation. This paper reports the relationship between consistency of SF concrete and admixing ratio of superplasticizer and cellulose viscous agent, but also the characteristics of specimens that are placed SF concrete having different consistency. The series of tests clarifies that SF concrete offers uniform and dense concrete structure without any vibration.
