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.
