Exterior concrete should be air entrained and at the minimum required strength prior to exposure to multiple freezing-and-thawing cycles. Problem #2 Concrete sets more slowly when it is cold but especially slow when temps are below 40℉. Cold weather conditions occur for up to 6 months in many parts of North America. A rapidly growing number of contractors have turned to hydronic heating equipment to help solve their cold-weather concreting problems.

Aug 20, Concrete curing blankets: these blankets create a layer of heat above the concrete, allowing water within the concrete mixture to evaporate  . Warmed-up aggregates and water are usually the most cost-effective means to control initial concrete temperature, although water and aggregate temperatures should not exceed °F (80°C) as a flash set might result. Crews must maintain the temperature of the mixed concrete above 50°F (10°C). Hot water and aggregates. Problem #2 Concrete sets more slowly when it is cold but especially slow when temps are below 40℉. Below 40℉ the hydration reaction basically stops and the concrete will gain strength at a very slow rate.

This spring has been unusually cold for much of the eastern United States, due largely to a mass of warm air over Greenland that has redirected air currents from north to south. To avoid carbonation of fresh  . Three types of heaters are used in cold-weather concrete construction: direct fired, indirect fired, and hydronic systems. Remember that you need to keep it above 50°F for the concrete to keep gaining strength. Placing decorative concrete in cold weather is no different than any other concrete, but here are a few extra tips: Keep a dial pocket thermometer or an infrared thermometer to test the concrete temperature. Concrete in cold weather absolutely does need to be cured—the surface can dry out even faster than in warm weather, if the concrete is warmer than the air. Remember the definition: If the air is below or expected to go below 40°F, then use cold weather techniques.
