The winter temperature in the northwest region of China is relatively low, and winter construction in cold areas can have adverse effects on the various properties of concrete.
Long term exposure to cold environments can increase the porosity and decrease the compactness of concrete, making it loose and brittle, seriously affecting its mechanical and durability properties.
Adding antifreeze can effectively lower the freezing point of liquid phase water in the internal pores of concrete, allowing concrete to undergo hydration reactions well under low temperature conditions, thereby significantly improving the frost resistance of concrete.
Therefore, researching high-performance antifreeze agents to improve the mechanical and durability properties of concrete in cold regions is of great practical significance.
