Many people don’t realize that after you pour concrete, it does not merely go from wet to dry. Chemical reactions take place as the mixture hardens. Therefore, when concrete mix is set in place and begins to cure, it generates heat. The concrete molecules bond with water molecules in a process called hydration. As the bonding process takes place, it releases heat. Since this process releases heat, it’s referred to as an exothermic reaction. According to the Portland Cement Association, every 100 pounds of cement used to make concrete adds 10 to 15 degrees Fahrenheit of heat. The larger the slab of concrete, the more heat is produced. But the heat created during the process can be damaging to the integrity of the concrete if not properly regulated. The target temperature for curing concrete is about 50 to 90 degrees Fahrenheit. If the concrete stays within that range, it reaches the best balance between final strength and overall time to cure.
Controlling Concrete Curing Temperatures
To keep a concrete slab within that temperature threshold, it sometimes needs a little outside help. On a cold day in Nevada, a concrete team might need to use external heating methods or insulation to increase the ambient temperature or the temperature of the mixture itself. Conversely, a hot day might bring too much ambient heat. A concrete finishing team then applies water, using evaporation to remove excess heat.
Another method to adjust the temperatures of the exothermic reactions is by adjusting the composition of the concrete mix. The amount of aggregate, sand, or cement in the mixture affects its curing temperature. Some concrete mixtures result in higher curing temperatures, while others are designed to heat up gradually and take longer to cure. Controlling the exothermic reaction helps avoid cracking or other types of concrete defects.
The Next Step for Durable Concrete
It takes a lot of effort to get a strong, stable concrete slab in place. With all the effort poured into the final product, it’s important to protect your investment.
