Abstract

In the cold-weathering concrete construction, it is important to ensure stable strength development of concrete in a low temperature environment. In this study, Non-curing cement(NCC) using the classified high fineness cement and self-heating powder was investigated for stable strength development without curing in a low temperature environment (less than $0^{\circ}C$). The actual size Mock-Up tests by various cement type and curing condition are performed to evaluate the strength development and hydration heat of concrete.

동절기 콘크리트 공사에서는 무엇보다도 저온환경에서의 콘크리트의 안정적인 품질 확보가 중요하다. 따라서 본 연구에서는 고분말도 발열분체를 적용하여 동절기($0^{\circ}C$이하)에서도 양생 없이 강도발현이 가능한 콘크리트를 개발하였으며, 이를 현장에 적용하기 위해 실 부재 사이즈의 Mock-Up 부재를 제작하여 개발기술의 현장적용 성능평가를 실시하였다.
