A Fundamental Study on the Addition Time and Method of Superplasticizing Agents of the Workability and Engineering Properties of Folwing Concrete

유동화 콘크리트의 시공성 및 공학적 특성에 미치는 고성능 감수제의 첨가시기 및 방법에 관한 기초적 연구

This is the study on the feature of workability and engineering properties of flowing concrete using the superplasticizing agents which is using to effect considerable reductions in water contents in the same level of consistemcy and workability. It is the aim of this study to compare workabili쇼 and engineering properties of flowing concrete according to the addition time and method of superplasticizing agents. In this experimental study, 2cm slump of concrete, 18cm slump of conventional concrete, two kinds of aggregates and addition time and method of superplasticizing agents of 0, 15, 30, 45, 60 and 90 minutes were included to analyze and investigate the workability and engineering properties of flowing concrete.
