Evaluation on Vapor Pressure of Ultra-high-strength Concrete by Heating Condition

가열조건에 따른 초고강도 콘크리트의 내부수증기압력 평가

Ultra-high-strength concrete exposed to high temperature is likely to cause spalling. Spalling is caused by the vapor pressure of the concrete, and the vapor pressure may be different depending on the heating conditions of the concrete. Therefore, in this study, a ring-type restrained specimen was fabricated using ultra-high-strength concrete and the vapor pressure generated in the concrete by heating condition(rapid and slow heating) was evaluated.
