Here in Nashville, the temperatures can really rise in the summer! Heat not only affects how comfortable you are or the amount you run your air conditioner, but it also affects concrete. As concrete contractors, we adjust our workflow for pouring concrete in hot weather.
The ideal temperature for pouring concrete is around 50 to 60 degrees Fahrenheit, but that doesn’t stop us from pouring you a beautiful concrete driveway in hot weather! In today’s blog post, we’ll share how hot weather conditions affect concrete as well as how we adjust to account for higher temperatures.

Effects of Hot Weather
Hot weather affects the speed with which water evaporates from the surface of freshly poured concrete. This accelerates the curing time of the concrete, which, in turn, affects the strength of the concrete. When the evaporation rate is high, there is a higher likelihood of surface cracking prior to setting. Reduction in set times due to hot weather makes concrete difficult to handle and means that the crew has to work faster to place and finish the concrete.
If the temperature changes drastically within the course of a day, concrete can also experience thermal cracking. For example, if the concrete is poured during a hot, sunny afternoon and the temperature drops quickly overnight, there can be cracking or shrinking.
Adjustments for Heat
While the effects of hot weather can damage your concrete, there are some adjustments that can be made to compensate for the temperature.
As we said earlier, the faster the concrete sets, the less strength there is in the curing process. Chemicals can be added to the concrete to increase its strength by accelerating or slowing down the workability, consistency, and durability of the concrete. Chemical additives can delay the chemical reaction that occurs during the setting process, allowing our concrete contractors more time to finish the concrete before it sets.
Water and Ice
It may sound overly simple, but water and ice can be used to keep the concrete cool! Aggregates can be sprayed with water or ice can be added during the concrete mixing process.
Shading & Windbreaks
Physical sunshades and windbreaks can help keep the site cooler and dryer. Plus, they help protect our crew from the heat as well.
