A Study on the Durability of Concrete made with Various Cements Containing Additive

시멘트 혼합재 첨가에 따른 콘크리트 내구 특성

This paper covers concrete durability made with portland cement type I and V, and granulated blast furnace slag blended cements 40 and 60%. Typical properties of cements and compressive strength development, drying shrinkage, carbonation, freezing and thawing properties of concretes were investigated. In addition, effects of CI penetration on various concretes with/without a freezing and thawing treatment were also studied. Portland cement type I and V were superior to the blended cement in the properties of compressive strength development, drying shrinkage, carbonation and freezing and thawing durability. In the respect of resistant of CI Blended cement showed better than the portland cement due to high permeability. But the blended cement with a freezing and thawing treatment presented a much decreased resistance of CI penetration.
