型号：YC-HDD
产地：北京
生产厂家：北京仪创时代科技有限公司
用途：本方法适用于测定混凝土试件在大气环境中且与盐接触的条件下，以能够经受的冻融循环次数或者表面剥落质量或超声波相对动弹性模量来表示的混凝土抗冻性能。
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.
