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.
How warm do concrete blankets keep concrete?
Not only do concrete blankets help maintain a temperature above 40 degrees, but they also lock in moisture. Moisture is a very important part of the curing process. It’s needed to prevent cracks and rapid drying. Working with concrete in extremely hot and dry weather is just as challenging as in the cold.
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 20xb0F
How well do concrete blankets work?
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 20xb0F. And since the setting process occurs so quickly, you’ll usually only need to rent one out for a couple of days.

It’s needed to prevent cracks and rapid drying. Working with concrete in extremely hot and dry weather is just as challenging as in the cold.
What can I use instead of a concrete blanket?
If blankets alone aren’t enough to keep the slab warm (or the walls for formed concrete) then you can use hydronic heating pipes or electric heating blankets laid on top of the slab and insulated. If the concrete is kept at around 50xb0F, protection can typically be removed after two days.
How long should you leave concrete blankets on?
After Lay and Finish is Completed, and Bleed Water has Evaporated, Cover the Concrete with Insulated Curing Blankets to Stabilize at the Constant Optimal Temperature. After about 72 Hours, Remove the Thermal Concrete Blankets and Allow the Slats to Air Dry.
What temperature should you use concrete blankets?
Use insulation blankets or heated enclosures to maintain concrete temperatures above 50xb0 degrees Fahrenheit for three to seven days. Use a good quality curing compound if you are unable to maintain concrete temperatures above 50xb0 degrees Fahrenheit for three to seven days.
Do concrete blankets keep the ground from freezing?
During the curing process concrete warms up from the inside. Concrete blankets lock heat in while keeping the cold out. They prevent water from freezing which allows curing to occur. This is why they’re also called curing blankets.
When should you put blankets on concrete?
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 20xb0F.
How cold can you pour concrete with blankets?
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 20xb0F.
What do you put in concrete to keep it from freezing?
This extra cement helps develop early strength. Maintain the concrete temperature above 40 degrees Fahrenheit for at least four more days after the use of the insulation blankets or heated enclosures.
How long does concrete need to set before freezing?
Blankets will keep your concrete warm even if the temperature goes below 20u2109. Use layers of blankets at corners and edges that could freeze. If blankets aren’t enough, try laying heating blankets on top of the slab or using hydronic heating pipes to keep the slab from freezing.
How long should I leave concrete blankets on?

The blankets have a closed cell foam, bubble and a reflective layer that provides insulation between the poly skins.
Can you use a tarp as a concrete blanket?
Not only do concrete blankets help maintain a temperature above 40 degrees, but they also lock in moisture. Moisture is a very important part of the curing process. It’s needed to prevent cracks and rapid drying. Working with concrete in extremely hot and dry weather is just as challenging as in the cold.
At what temperature do you need to use concrete blankets?
You can usually remove the blankets after 2-3 days but watch the temperature. If it’s extremely cold then keep them on. I’ll sometimes cover concrete for 7-10 days. Don’t use too much water in your concrete mix.
How long does concrete need to be protected from freezing?
Use insulation blankets or heated enclosures to maintain concrete temperatures above 50xb0 degrees Fahrenheit for three to seven days. Use a good quality curing compound if you are unable to maintain concrete temperatures above 50xb0 degrees Fahrenheit for three to seven days.
What is the lowest temperature concrete will cure?
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 can I use as a concrete blanket?
You can purchase an insulated concrete curing blanket from most DIY stores, but it’s cheaper to simply use a sheet of plastic. Choose polyethylene plastic that is at least 4 millimeters in thickness
Why do you need concrete blankets?
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 do you add to concrete to keep it from freezing?
During the curing process concrete warms up from the inside. Concrete blankets lock heat in while keeping the cold out. They prevent water from freezing which allows curing to occur. This is why they’re also called curing blankets.
Can you leave concrete blankets on too long?
You can usually remove the blankets after 2-3 days but watch the temperature. If it’s extremely cold then keep them on. I’ll sometimes cover concrete for 7-10 days. Don’t use too much water in your concrete mix.
How long do I need to keep concrete warm?

How long should concrete be covered in freezing weather?
The process of curing concrete becomes more challenging in cold weather since, to properly set and reach maximum strength, fresh concrete must be protected from freezing for at least the first 24 hours, or until it reaches a minimum strength of 500 pounds per square inch (psi).
