염분환경하 콘크리트 경화체의 내구성에 미치는 혼합재의 영향 II. 콘크리트의 동결융해저항성

Effect of Blending Materials on the Durability of Concrete II. Freezing and Thawing Resistance of Concrete

It is well-known that concretes under sea water environment show remarkably degrading phenomena physically by repeatable freeze-thawing action and chemically by penetration of soluted ions in sea water. In this study the influences of type of blending materials, their dosage and W/C ratio on freeze-thawing resistances of hardened cement concrete using foy ash, ground blast furnace slag, silica fume, EVA and SBR under sea-water environment were investigated.
