Pouring concrete is an extremely specific job. It includes particular materials and tools. Also, it needs accurate execution to keep structures stable for a lot of years. Aside from that, concreting revolves around conditions outside. This includes cold and hot weather. Extreme temperatures can make pouring concrete an even more accurate process.
If you’re planning to pour concrete without the help of a concrete contractor and service Hoover Birmingham, here are several tips you can follow when pouring concrete during hot weather.
Preventing Issues When Pouring Concrete During Hot Weather
There are a couple of tricks and tips that you can try if you pour concrete in hot weather. These tips include:
- To prevent it from heating, cover every tool while not in use. Hot tools will only act as a catalyst to humidity and heat in the air.
- Pour the concrete after the roof and walls are built. This will manage better the heat by protecting the concrete from the UV rays of the sun.
- Cool intentionally one or more of the aggregates included in the concrete mixture. If you do this, the concrete will be cool enough to ensure the heat in the area.
- If you make use of evaporation retarders, sheeting, windbreakers, and sunshades, you can protect concrete from external factors.
- You’ve got to be ready for escalated curing. This means you’ve got to make necessary adjustments to create the ideal results, whether this means hiring more workers, using more tools, or both.
- Moistening the subgrade. The subgrade has a high possibility of staying moist since it won’t be exposed to the sun after you pour the concrete.
- Pour concrete at cooler times. This includes late at night or early in the morning. With this, you will not have to change your techniques and you can proceed as normal.
Issues That Can Occur When Pouring Concrete when The Weather is Hot
When creating a ready mix concrete, water plays a big role. It is the capability of controlling the moisture inside the concrete that enables proper curing and setting. Issues can happen because of too little or too much moisture. Too little moisture is a common issue when pouring concrete during hot weather. Professionals have figured out that temperatures of more than 80° F can be threatening to the process of pouring concrete. Here are several issues that can occur:
- Cold joints can form
- Untimely curing and setting
- Loss of long-term strength
- Greater chance for thermal and plastic cracking
- Accelerated slump loss
For those who don’t know, it’s a lot better if the concrete cools for a longer period. The mixture will harden and takes form as it cools. Therefore, hot weather can lower cooling time. This stops the mixture from achieving its optimal strength. It isn’t just hot weather either. High humidity and high winds can also contribute to unnecessary rapid cooling.
If you don’t want these things to happen, you can follow the tips above. Aside from that, you should also hire a professional to pour the concrete.
