In Louisiana, it’s been exceptionally hot these past few days.
With a heat index of 109° F, concrete contractors in particular have had to take special precautions when pouring concrete outdoors.
There are many complications that come with pouring concrete in extreme heat, aside from health concerns.
Let’s take a look.
The risks of pouring concrete when it’s too hot outside
Fortunately (for the concrete only), in Louisiana, we don’t experience many low-humidity or windy days. These factors can complicate the pour and require special adjustments to be made.
The following issues can arise when pouring in extreme heat:
- Decreased durability and strength,
- Higher risk of thermal cracking,
- Higher risk of drying shrinkage,
- Cold joint formations,
- Higher risk of slumping, and
- Higher risk of finishing problems.
Is it possible to pour concrete in extreme heat?

In short, yes, it is possible to pour in extreme heat by taking the proper precautions:
- Plan in advance. The mixed concrete will need to be poured more quickly than usual, so we always check our routes ahead of time to make sure there won’t be any delivery delays.
- Expand the size of the crew. The more hands on deck, the faster the job will be completed.
- Counteract the effects of the heat on the concrete during all stages of the pour. This may include blocking the sun with portable shade or tenting an area.
