Why Is Hot Weather a Problem for Concrete?

July 12, 2019

Whether you’re a big fan of warm summer weather or are already looking forward to things starting to cool down again this fall, there are likely some outdoor projects that you want to wrap up over the coming summer months. If you have any projects or jobs coming up that require concrete pouring, you have to take into account the role that weather and temperature will play. Read on for some information from our concrete recycling company in Toledo, OH.

How does heat affect concrete?

Concrete sets through a process of hydration. As concrete sets, cement absorbs water and crystals start to form around cement particles. These crystals make up the basis of the structure of set concrete. This process of hydration generates heat, and if there is external heat at play, it can contribute to a much more rapid setting process.

A lot of people think that faster setting is a good thing, but it can actually have a lot of negative impacts on the long-term strength, durability and longevity of your concrete. When temperatures are high, crystals will form more quickly and concrete will set faster, but the concrete hardens so rapidly that those crystals are never able to grow stronger and more resilient.

Another important factor to consider is evaporation and surface shrinkage. When the sun is beating down on wet concrete, the surface dries more rapidly. This rapid drying through evaporation can cause shrinkage and cracking in your concrete that takes a toll on the overall structural integrity of your concrete surface. Hot weather can also affect your ability to mix concrete with the right ratios. For proper application, you need a certain ratio of cement, aggregate, water and air, but heat can throw levels of air and water off balance. To account for these variables, a lot of concrete contractors have to add more water and use cooling ingredients for proper concrete application.

What you can do about it

If you’re pouring concrete in hot weather, there are a few things you should keep in mind. First of all, make sure that you’re timing your project for when the weather is as cool as possible. Pouring concrete at a cooler time of day will help you avoid a lot of the issues associated with hot weather and direct sunlight. If you pour your concrete in the heat, monitor its condition for at least a month to determine whether there are any problems that need to be addressed. If your concrete pouring project wasn’t successful, reach out to a company that provides concrete recycling in Toledo, OH for assistance so that you can start with a clean slate.
