Curing concrete is the process of maintaining moisture and temperature when you lay concrete so that the concrete is able to reach its maximum designed strength. When you properly cure concrete it makes the concrete more durable because properly cured concrete will achieve a harder surface. Controlling the moisture and temperature while the concrete is curing will make the future durability of the concrete more predictable. This means that if you ordered 5000psi concrete you will have a better chance of actually getting 5000psi concrete.
This article will teach you the steps to properly cure concrete.
In this article, you will find information about:
Keeping concrete moist is critical to proper concrete curing. There are two preferred ways to slow the moisture loss and properly cure concrete: plastic covering or applying a curing and sealing compound.
Curing Concrete By Covering With Plastic
Curing Concrete By Coating With A Curing Compound
A curing compound is a sprayed on liquid that forms a membrane on the surface of the concrete that slows the moisture loss from the concrete. There are two products that are typically used: Curing compound and Cure and Seal compound. The cure and seal compound provides the added benefit of sealing the surface to enhance the concrete surfaces ability to resist penetration of water and chemicals.
Temperature is the second factor in properly curing concrete. There are severaly ways to control temperature when curing concrete and which one you use depends on the weather.
Freshly laid concrete produces heat but too much heat is bad for the curing process, it reduces the finished strenth of the concrete. When the weather is hot it is important to keep the temperature of the concrete down.
When the weather is cold the curing process is slowed down. If the concrete is allowed to freeze there is an increased chance of scaling and an overall weaker concrete.
