There are several conditions to consider when installing commercial concrete. These conditions include environmental factors like weather, as well as circumstantial factors such as how long you can close the area to allow concrete to properly cure.
4 Conditions for Optimal Commercial Concrete Installation
Weather, available working hours, concrete mix, and location are all important factors to consider when installing commercial concrete. While these are not the only factors to consider, they are among the most important.
Temperature plays an important role in how well commercial concrete installation turns out. For best results, the key is to avoid installing concrete at the hottest and coldest times of year, opting instead for mild weather. Therefore, fall is typically the best time of year to install commercial concrete in Tennessee.
The fall offers reduced humidity along with warm days and cooler nights, which helps optimize the curing process. Ultimately, improving concrete durability and overall strength. Temperature influences how fast concrete material dries. The warmer the weather, the quicker concrete will dry. The cooler the weather, the slower it will dry.
Concrete sets in around 5 hours when the temperature is at 70 degrees, and it will take closer to 20 hours to set (if it doesn’t freeze first) when the temperature is 30 degrees. When temperatures dip too low, materials are at risk of freezing before they have a chance to dry. Thus, causing cracks and other issues. Plus, the amount of time concrete takes to set will influence its overall durability.
There are special tools and equipment that can be used to help facilitate concrete installation in un-ideal weather, such as warming blankets, tents, unique curing compound blends, ground heaters, and so forth.
Available Working Hours
How long must you shut down surface areas to allow concrete to cure? Surfaces need at least 24 to 48 hours to cure. From there, it takes another 7 days for concrete to reach 70% of its full strength. Concrete is considered at its full strength 28 days post-construction. Light traffic may re-enter surfaces after 24 to 48 hours. Heavy machinery and equipment should remain off surfaces for longer than this. In some cases, it is recommended to keep traffic off surfaces for 7 days.
There are certain techniques and tools that can be utilized to help speed up this process for commercial locations. Another option is to pour concrete in sections, shutting down different areas at one time. Talk to us about your unique circumstances, we are happy to help you determine the best solution.
The Concrete Mix
The concrete mix applied to a surface should be specially formulated for specific uses, requirements, and so forth. For instance, are there are any durability issues to consider? Will heavy machinery navigate over finished surfaces—or rather, what is the total load bearing rate required?
As mentioned before, weather is an important element to consider as well. Thermal issues, such as temperature rise, must be taken into consideration when formulating the proper concrete mix. There are ways to limit thermal issues, such as using GGBSF and a cool mix that insulates the formwork.
Location of Concrete Installation
Location is yet another important consideration. How easy is it to access the area? Keep in mind that cement equipment can be cumbersome. The location and its accessibility can impact how long the job will take, and how long the area must be closed off with yellow tape.
