In order to understand why the right temperature is so important for pouring concrete, it's important to know the basics of how concrete works. This means that pouring concrete during summer or winter months may come with additional challenges. It doesn’t matter how big or small your concrete pour is, the first step is to prepare the ground. Considering concrete needs to dry once it is poured, many might be under the impression that a hot sunny day is ideal for it. With the proper insulation covering all areas exposed to the cold it will maintain this temperature in most cases. The seasonal temperatures that have an effect on the foundation are: Average daily temperature is below 40 degrees; The air temperature is not greater than 50 degrees for a 24-hour period; Problems Cold Weather Presents to Foundations.

The Mid-Atlantic states tend to experience cold winters that bring a fair amount of snow—not an ideal time for concrete work. The early spring also can work before the temperature heats up. James R. Baty II Question: Concrete foundation pours in cold weather will be affected by temperatures in the mid 30s to mid 40s or lower. The current American Concrete Institute (ACI) definition of cold-weather concreting, as stated in ACI 306 is, “a period when for more than three successive days the average daily air temperature drops below 40 degrees Fahrenheit and stays below 50 degrees Fahrenheit for more than one-half of any 24 hour period.” There are a few ways to keep the concrete within the proper temperature range, such as: Laying concrete in ideal weather conditions requires skill, knowledge, and experience. While the concrete will harden within a relatively short time after the initial pour, the hydration process will continue for weeks, even months thereafter. Even when pouring concrete in extreme temperatures, there are steps that professionals can take to achieve success. Synopsis: When senior editor Andy Engel decided to build a freestanding garage next to his house, he opted for a frost-protected shallow foundation rather than a conventional slab with footings below frost depth and a stemwall atop the footings. For more details, see our. There are some variables when it comes to the best time of year to mix and pour cement for a concrete patio, path, or other outdoor project.

This is actually not true, as the best possible conditions for pouring concrete come in spring when the temperature is consistently in the 50s and the skies are cloudy. The temperature of the concrete must therefore be maintained above its freezing point until its compressive strength is 500 psi. Concrete Temperature limits are established to ensure that high quality concrete with specified requirements are produced. The poured foundation should be kept as uniform as possible in temperature during the curing process. Finally, if the temperature is too cold, a heater and enclosure are used to maintain temperatures above freezing. Temperature extremes make it difficult to properly cure concrete. In general, temperatures between 50 and 90 degrees Fahrenheit are typically fine for curing concrete. The best seasons tend to be winter and spring when temperatures are relatively mild.
