Freezing in a 5% NaCl solution and thawing in the same solution. Structures exposed to de-icing salts or seawater. Freezing in air at lower temperatures (down to -50∘Cnegative 50 raised to the composed with power C ) to speed up results. Urgent quality control or high-grade concrete. Accelerated Method 2
: Once the target number of cycles (the "F" grade) is reached, test the "main group" for compressive strength. 5. Evaluation Criteria
High-concentration salt saturation and specialized cooling profiles. Road, bridge, and airfield pavements. 4. Step-by-Step Procedure
: Test a "control group" of specimens for compressive strength before any freeze-thaw cycles. Cycling :
