用途：本方法適用于測定混凝土試件在大氣環境中且與鹽接觸的條件下，以能夠經受的凍融循環次數或者表面剝落質量或超聲波相對動彈性模量來表示的混凝土抗凍性能。
Model: YC-HDD
Origin: Beijing
Manufacturer: Beijing Yichuang Times Technology Co., Ltd.
Purpose: This method is suitable for determining the frost resistance of concrete specimens under atmospheric conditions and in contact with salt. The frost resistance is expressed by the number of freeze-thaw cycles the specimens can withstand, the mass of surface scaling, or the relative dynamic elastic modulus measured by ultrasonic testing.
