Concrete Split Rapid Freeze-Thaw Testing Machine Cement Frost Resistance Tester Concrete Durability Coefficient Test Equipment
Concrete Split Rapid Freeze-Thaw Testing Machine Cement Frost Resistance Tester Concrete Durability Coefficient Test Equipment
Test Principle
The frost resistance of concrete is evaluated by the number of rapid freeze-thaw cycles that concrete specimens can endure under the condition of water freezing and water thawing. It is used to confirm the frost resistance grade of concrete and calculate verify the durability coefficient of concrete.
