Extreme weather concrete
Keep working even when the thermometer takes a dip
As the temperature drops, finishing concrete becomes a challenge. IMI has developed concrete mixes that are designed for specific cold weather conditions.

The imix SureSet series are three mixes batched for specific ambient temperature ranges. They are guaranteed to set up in four hours or less. SureSet provides excellent finishability and reduces common cold weather problems, such as scaling and pop outs. There are restrictions in using SureSet. Forms and sub-grade must be free of frozen material, ice, and frost prior to placement. You must use the proper SureSet mix in accordance to ambient temperature. The concrete must be unloaded within 15 minutes after arrival on job site. During finishing, no free moisture (water, snow, rain, etc.) can be added to the surface. Slumps must not exceed eight inches. Proper finishing techniques according to ACI 306 (Cold Weather Concrete) must be followed.

imix Freezeguard is an admixture that can be used with other standard, air-entrained batches in temperatures down to 20° F. Freezeguard is chloride free, so it will not discolor the concrete. It lowers the temperature at which water molecules freeze, so it does not need to be covered or warmed with blankets to retain its heat and gain strength. However, no extra moisture can be added to the mix. This includes watering, rain, snow, etc. You can place imix Freezeguard up to slumps of six inches. Curing compound must be applied as soon as you complete finishing the concrete. Ambient temperatures cannot drop below 20° F.
