When concrete is placed in cold weather, the mix sets up slower than normal. This increases the risk the water will freeze before the batch fully hardens. Frozen concrete does not set up correctly, and will likely need replacement in the future. Fortunately, adding a concrete accelerator to the mix increases the speed of the set time, reducing the amount of time the water in the mix is vulnerable to freezing. Fritz-Pak’s Non-Chloride Accelerator offers increased set time in a convenient water-soluble bag. One bag of NCA can speed up the set time by up to one hour.
Using a chloride based concrete accelerator increases the risk of steel corrosion and efflorescence in concrete. Fritz-Pak’s NCA offers the same benefits without the added risk. Check out the videos below to learn more.

Fritz-Pak NCA is compatible with most concrete admixtures. When used with other admixtures, each one should be dispensed separately into the mix. Effectiveness of NCA is dependent on the proportion of C3A to SO3 in the cement. Higher acceleration will be obtained in cements with ratios greater than 4.0. In general, higher accelerations will be obtained in mixes with Type I, III or white cement.
