An Analytic Study on Early aged Freezing Damage Prevention and Thermal Crack Control of Concrete in Cold-Weathering Mat Foundation Construction

동절기 매트기초공사시 콘크리트의 초기동해방지 및 온도충격제어에 관한 해석적 연구

This study is peformed for checking the limitation and application of each curing/heating methods on cold-weathering mat foundation construction, considering temperature control, early strength security and temperature declination range limit, by means of concrete material properties and thermal analysis technique that were published previously. In the result of this analysis, we checked the open air temperature and mat depth that are possible to apply each curing/heating methods on cold-weathering construction and found curing/heating time of each methods that is able to prevent early aged freezing damage and thermal crack
