Concrete is susceptible to freeze-thaw cycles in cold regions, leading to structural degradation.
The frost resistance of concrete refers to the ability of concrete to withstand multiple freeze-thaw cycles in a saturated water state without damage.
Existing research is mostly based on macroscopic experimental indicators (such as strength loss, mass loss rate, dynamic elastic modulus, anti peeling ability, ultrasonic wave velocity loss, etc.
) to explore the frost resistance of concrete, but lacks microscopic and macroscopic correlation analysis.
This article systematically studies the mechanism of freeze-thaw failure, material and process optimization, and environmental coupling effects, in order to provide technical references for improving the frost resistance of concrete.
