: Cast or cut specimens from the concrete mix or structure. Ensure they are free of visible defects.

: Concrete is assigned a frost resistance grade (e.g., F100, F200), where the number represents the minimum number of freeze-thaw cycles the concrete can survive while meeting specific strength and mass loss criteria. 2. General Testing Requirements gost 10060 2017

: Samples must be saturated with water (or a 5% sodium chloride solution for road/airfield concrete) before the freezing process starts. : Cast or cut specimens from the concrete mix or structure

: No visible cracks, chips, or delamination are present. 6. Documentation and Reporting The final test report must include: Concrete mix design and project identification. The specific method used (Basic vs. Accelerated). Dimensions and number of specimens. The final result (the achieved F grade). Any deviations from the standard procedure. If you'd like, I can: Transfer specimens to the thawing tank.

: The average mass loss due to scaling and surface damage does not exceed 2% .

Place specimens in the freezing chamber for the required duration. Transfer specimens to the thawing tank.
