Why should we add antifreeze to concrete? Bozhou antifreeze manufacturer Fuyang early strength antifreeze

The main purpose of adding antifreeze to concrete is to maintain a sufficient liquid phase at negative temperatures so that the hydration of cement can continue; after switching to positive temperatures, the concrete The strength can be further increased and reach or exceed the design label.

Concrete poured in winter suffers premature freezing without adding antifreeze, which will greatly reduce the ultimate strength. The strength loss rate may reach 50% of the design mark, and even cause damage to the overall structure. destroy.

A certain amount of antifreeze mixed into the concrete mixing water will lower the freezing point of the aqueous solution. The degree of reduction in the freezing point depends on the type and dosage of the antifreeze. Depends on the concentration of the solution. The effectiveness of antifreeze depends largely on the concentration of the solution and the negative temperatures to which the concrete is subjected during hardening.
