The Construction of High Strength Concrete (500kg/$\textrm{cm}^2$) with Fly-Ash for SAMSUNG APT in San Bon Area

산본 삼성고층 APT에 플라이 애쉬를 혼입한 500kg/$\textrm{cm}^2$이상의 고강도 콘크리트의 최적배합, 시공 및 구조적 연구

To investigate the properties of High Strength Concrete with Fly-Ash for SAMSUNG San Bon high rised apartment, following variables has been strudied and constructed, successfully. Major variables are F/(F+C), W/C, S/A, Pumping Method, etc.. The results show that 15% of F/(F+C) is the best properties for compressive strength of concrete, temperature reduction and workability.
