저온환경하 콘크리트 표면동결 방지를 위한 단열 및 발열거푸집 개발에 관한 연구

Abstract

Domestic construction market is congested enough at the moment cause enterprises to enter overseas market such as Mongolia and Russia. However most previous studies conducted at a temperature above freezing. In this study, thermal performance evaluation and compressive strength test are conducted on cement mortar at a low temperature below freezing. Accelerator for freeze protection is used to prevent freezing of mixing water. Cement mortar is placed in each of insulated and heating forms. Especially, high fineness cement is considered to use with insulated form. Hydration heat of quicklime is used for heating form in this study. The analysis of this study confirmed that high fineness cement with insulated form and heating form can be suitable to be used in low temperature environment.
