An Experimental Study on the High Strength Concrete Properties for Mixing Methods and Elapsed time

고강도 콘크리트의 배합방법과 운반특성에 관한 실험적 연구

The aim of this study is to develop economical High-Strength and High-Quality Concrete, and to assure quality control of Concrete in the field. For this purpose, Five types of Mixing Methods are examined and the relationship between slump loss and slump recovery by transport is studied. As a result, workability and strength are dependent on the Mixing Method, although the Mixing proportions are same, Also, adding admixture in the field is proposed as an alternative to consider the relationship between slump loss and slump recovery.
