Spalling and Ultrasonic Pulse Transmission Time of Ring-Type Restrained Concrete exposed to High Temperature
고온에 노출된 링형 강관 구속 콘크리트의 폭렬 및 초음파투과시간
Abstract
In this study, the spalling and ultrasonic pulse transmission time of concrete were investigated according to compressive strength during heating. As a result, the higher the compressive strength of the concrete, the more the explosion occurs, which affects the cross-sectional loss and the spalling fragment size. Also, ultrasonic pulse transmission time was found to be strongly influenced by the section loss of concrete.
