동절기 환경에서 고로슬래그 혼입 콘크리트의 적산온도 기반 압축강도 예측 연구

Abstract

Recently, as blast furnace slag concrete has become widely used, managing the strength of concrete has become important. mSn is a method of correcting the difference in strength between standard cured specimens and concrete exposed to changes in temperature. In this study, mock-up concrete mixed with blast furnace slag that simulated a structural column was produced in a winter environment. As a result, a gap in maturity occurred between the central and outer parts of the concrete, and the difference in predicted strength became larger as the blast furnace slag mixing ratio increased.
