A Study On the Mix Design and Quality Control System of High Strength Concrete for the Construct ion of High Rise Complex Structure

초고층 주상복합구조물에 적용한 고강도 콘크리트의 배합설계 및 품질관리 시스템에 관한 연구

The purposes of this study were mix design and quality control of high strength concrete for the construction of high rise complex structure. Desired performances of this high strength concrete were slump flow 50$\pm$10cm, air content 4.5$\pm$1.5% and design strength 400kgf/$cm^2$. Experimental flow was that optimal mix design was selected in the indoor experiment and after that, producing test was done in the batcher plant. Excel lent results of experiment was obtained from binder content 475kg/$m^2$ with replacement ratio 10% of fly ash. The results of field application of high strength concrete was sufficiently satisfied both flowability and compressive strength.
