If you want to cure concrete in cold weather, you should have the required material and knowledge. Water, humidity, temperature and even snow can complicate cold weather concreting. Concrete should not ever be poured on freeze ground. Concrete hydration can be affected by a temperature drop below the freezing point. Continue reading to learn our tips on how to cure concrete in cold seasons. Two important things to remember when placing concrete in cold climate are that you might need different materials and what surfaces need protection. Certain materials may produce or even increase heat. These materials include chemicals.
Concrete sets slower when it’s cold. It will slow down at 50°F. Concrete curing will stop once it reaches 40°F. Concrete curing should take place at around 80 degrees F. Concrete that has not been cured for at least 48 hours may freeze, which can lead to concrete losing its strength and weakening your finished product. You don’t want this. There is a temperature difference between concrete and air. When it’s cold outside, the concrete will need to be protected until it can handle the cold on its own. Rule #1: Concrete is safe when it has reached 500 PSI. At this point, concrete has reached 500 psi compression strength.
However, concrete doesn’t need to be damaged by water. Hydration of cement has used enough water in the mixture so that it won’t freeze. This will occur with most concrete even at 50 degrees F. Use blankets or tarps to protect concrete from the elements. Or, you can use tenting. You must first ensure that the water-to-cement ratio is correct. This ratio should never exceed 0.40 in temperatures below the freezing mark. Make your concrete set quicker by changing the mix. To increase the speed of concrete development, change the mix. To prevent the concrete from freezing, you can use either a polyethene or heated concrete curing cover, or a propane heater.
