低温环境下超声波在混凝土中传播速度的研究
Study on Ultrasonic Wave Velocity in Concrete in Low Temperature
摘要
Abstract
The ultrasonic wave technique has been used widely. It is important to investigate ultrasonic wave velocity in concrete under different environmental temperature (especially at low temperature). In this study, the ultrasonic wave velocity in concrete was studied by means of the opposite measure method under the temperature of -30 ℃ up to 10 ℃. The experimental results show that the ultrasonic wave velocity increases with the decrease of environmental temperature.关键词
