Concrete Antifreeze (Kimifrost AF)

Kimifrost AF concrete antifreeze admixture is designed for cold-weather concreting at sub-zero temperatures. When the water in fresh concrete freezes, the expanding ice stresses the concrete and cement hydration stops; by lowering the freezing point of the mix water, this admixture keeps hydration going in cold weather. The dose is chosen from the ambient temperature as a starting point and optimised for the mix design and site conditions; the technical team sets the exact dose for each project. Concrete antifreeze complements thermal curing and covering; it does not replace them. Contact us to choose a dose and request a sample.

Frequently Asked Questions

Down to what temperature is Kimifrost AF effective?

Kimifrost AF is effective down to -15°C depending on dosage. Typical dosage ranges from 2% to 6% by weight of cement, adjusted based on ambient temperature.

Does concrete antifreeze replace thermal curing?

Concrete antifreeze supplements thermal curing, it does not replace it. At very low temperatures, simultaneous use of antifreeze and thermal blankets gives better results.
