홈페이지논문 초록 (Abstract)
Recently skyscrapers with high-strength concrete come to the spotlight internationally and main downtown buildings in the world get ultra higher-storied. However, Korea avoids using high-strength concrete because of the reasons as a lack of its construction experience and study. Therefore, the purpose of the study was to make a close inquiry into each kind of engineering properties with high-strength concrete of 80MPa and to select the optimum combination of high-strength concrete with good applicability and placeability. The study set up its condition of testing combination as W/B(25%), S/a(45%) and W(160㎏/㎥) and enforced experiments, mixing and adding each kind of binders in many ways. Also, the study used the minimal quantity of superplasticizer with in a scope to satisfy slumpflow of its target. As the result, combination of type Ⅱ showed good results in flowability, strength properties and durability.
