초기동해가 결합재를 변화시킨 콘크리트의 압축강도에 미치는 영향

Abstract

Recently, the concrete using multicomponent blended cement is being required to increase the resistance against early-frost damage. Thus, the purpose of this study is to propose the use of the concrete containing multicomponent blended cement as one of the alternative for concrete structure exposed early-frost damage. For this purpose, the concrete containing ordinary portland cement (PLC), binary blended cement (add : Ground Granulated Blast Slag), ternary blended cement (add : Fly ash), and quaternary blended cement (add : Mata-kaolin) were made for water-binder ratio of 50%, and then the compressive strength such as the concrete exposed early-frost damage were estimated for the concrete containing binary blended cement, ternary blended cement, and quaternary blended cement respectively. It was observed from the test that the compressive strength of the concrete containing PLC were found to be much better than that of the case containing multicomponent blended cement. It's necessary to ensure of quality control for early-frost damage in winter.
