Concrete blankets are incredibly effective at keeping the material warm during its curing process. In fact, these blankets can keep concrete at an ideal temperature even when the weather drops below 20°F. And since the setting process occurs so quickly, you’ll usually only need to rent one out for a couple of days.

What can I use for a concrete blanket?

These insulated thermal tarps can be used as concrete curing blankets, temporary curtain walls, or temporary heat enclosure, making them a versatile tool for creating the proper temperature environment for curing concrete.

What is the R value of a concrete blanket?

These Concrete Curing Blankets have high quality 6 mil Poly skins that create an R-Value of 5.11. This durable skin is a woven with reinforced poly that has a Black top surface and Silver bottom. The blankets have a closed cell foam, bubble and a reflective layer that provides insulation between the poly skins.

What temperature should you use concrete blankets?

Use insulation blankets or heated enclosures to maintain concrete temperatures above 50° degrees Fahrenheit for three to seven days. Use a good quality curing compound if you are unable to maintain concrete temperatures above 50° degrees Fahrenheit for three to seven days.

Will concrete blankets keep concrete from freezing?

For flatwork, the traditional, and still the best way, to protect concrete from the cold is to cover it with blankets after it’s been finished. Since the ground is a bit warmer and the concrete generates its own heat, blankets will keep it warm even if the temperature goes below 20°F.

How cold are concrete blankets good for?

Concrete curing blankets are essential if your working in cold weather. When temperatures drop below 40 degrees Fahrenheit, water inside the concrete mixture can freeze which causes structural damage. During the curing process concrete warms up from the inside.

Should I cover my concrete with plastic?

Plastic Sheeting Can Permanently Discolor Concrete. Adverse weather conditions such as rain, snow, or freezing temperatures often make it necessary to protect concrete by covering it. One of the most effective materials to guard against rain is plastic sheeting (visqueen).

How long does concrete need to be protected from freezing?

Freshly laid concrete must be protected from freezing for at least the first 24 hours. Because water is a main component of any concrete mix it is very important that concrete being laid in cold weather is protected as much as possible from freezing after it is poured.

What is an insulated tarp?

Insulated Tarps are winter enclosure tarpaulins used in cold climate regions during general construction and industrial maintenance. Insulated Tarps are made 8×8 weave poly tarp layered closed cell PE foam cores. These tarps are designed to insulate and control temperatures inside heated enclosures.

What temperature is too cold for concrete?

Experts agree—the best temperature to pour concrete is between 40° – 60°F. When temperatures dip below 40°F, the chemical reactions that strengthen concrete slow down and can lead to weaker concrete.

When should you cover concrete in cold weather?

At specified curing temperatures, well-portioned concrete mixtures should attain this strength within 24 to 48 hours. Therefore, it is critical that newly placed concrete be protected from freezing for the first 24 to 48 hours or until the concrete attains a strength of approximately 500 psi.

What is the lowest temperature concrete will cure?

At 25 to 27 degrees Fahrenheit, the freezing of pore water in curing concrete will halt hydration – and the curing process.
