How do Concrete blankets work?
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. Most are just thick insulated blankets but some designs have electric heaters built in. These can be used to keep concrete warm when insulation alone isn’t enough.
Why grip-rite blankets?
Available in three styles, Grip-Rite is the only blanket on the market with a low 0.87 Perm rating, providing superior vapor block during curing Each blanket individually wrapped in weather resistant poly tarp and secured with banding These blankets stack, ship and store better than any blanket on the market
How do concrete curing blankets work?
They work by holding in heat and keeping cold out. This method if insulating concrete is a viable alternative to changing up the cement/water ratio or using a heating source in an enclosed work area. Concrete blankets offer the R-factor, a.k.a. thermal resistance, needed to keep concrete projects from freezing.
What are concrete curing blankets made of?
Concrete Blankets - 1-1/2" Thick Made with interior PE Foam Core and a Polyethylene Exterior.
When should concrete blankets be used?
Use concrete curing blankets to prevent freezing and keep the concrete at an optimal curing temperature. Use insulation blankets or heated enclosures to maintain concrete temperatures above 50 degrees Fahrenheit for three to seven days.
How long should concrete cure before removing blankets?
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.
At what temperature should you blanket concrete?
Experts agree that the best temperature to pour concrete is between 50-60 °F. The necessary chemical reactions that set and strengthen concrete slow significantly below 50 °F and are almost non-existent below 40 °F.
What temperature should it be to cover concrete?
The goal is to make sure the concrete is poured and placed at a temperature of at least 40 degrees Fahrenheit and kept there for a period of time appropriate for the type of concrete and its intended use.
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.
How many days after pouring concrete can it freeze?
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.
Should I cover concrete after pouring?
If the concrete is still fresh (around 2-4 hours after pouring), it's important to cover the surface to protect it.
Can you leave concrete blankets on too long?
Fresh concrete frozen during the first 24 hours can lose 50% of its potential 28 day strength! Use insulation blankets or heated enclosures to maintain concrete temperatures above 50° degrees Fahrenheit for three to seven days.
What happens if you dont water concrete?
Concrete that is not moist-cured at all dries too rapidly, and reaches less than half its potential design strength. It will also have a greater number of shrinkage cracks.
How long does 4 inches of concrete take to cure?
The general rule of thumb is that concrete takes about 28 days to dry for every inch of slab thickness. Within 24 to 48 hours, the concrete will be ready for foot traffic.

What is concrete curing compound?
A curing compound is a liquid substance that is added as a surface coating on freshly installed concrete. Curing compounds are used to reduce the loss of water or heat in order to create ideal conditions that are favourable to the concrete formation.
What is dissipating curing compound?
DC WB DISSIPATING CURE 2519 is a 100% hydrocarbon resin, water base curing compound for fresh concrete. Designed to adhere to freshly placed concrete and enhance its overall strength, TK-2519 DC WB provides excellent curing properties and moisture retention for maximum surface density and hardness.
How do insulated blankets work?
The blankets work to keep you warm by their very design. As an impermeable metalized plastic sheet, they trap up to 90% of the radiated body heat that would normally be dispersed into the environment. So they mainly keep us warm with the heat we're already always generating and losing!
What is a hydracure blanket?
Hydracure concrete curing blankets effectively trap water, providing improved hydration, less discolouration and a more evenly cured concrete slab than other blankets on the market.
Is moisture absorbed into blankets?
Moisture is not absorbed into blankets making removal faster and lighter.
How to Choose the Right Insulated Tarp
Since your property’s maintenance is highly dependent on how effectively an insulated tarp protects it during harsh weather situations, it’s a must to choose one that meets your expectations. Following these tips will help you out:
How to Choose an Effective Curing Blanket
You’ll need a high-quality curing blanket when the aim is to preserve the layer of concrete you’ve just poured onto the floor of a construction site. Its application is most practical in extreme climate, i.e. in cold. The end result should be that the construction project is able to strongly hold concrete.
The Takeaway
Remember that various sellers will claim that they offer the most effective insulated tarps and curing blankets. But it’s up to you to assess if their products will actually meet your expectations. Look for credibility, read the reviews, ask around, and never settle for less.
What is dissipating cure?
Dissipating cures use cheap resins to form a membrane on the surface that holds in the moisture assisting in curing the slab. Most of these dissipating cures adhere to ASTM C309 which often dictates the curing compound to be used.
Does siloxanes cure concrete?
Good on those who mentioned it earlier. Similarly, other penetrating chemistries, such as silanes and siloxanes (two sides of the same coin) also do not cure concrete. Dissipating resins are formulated with hydrocarbon resins.
Do film forming compounds cure concrete?
Use of a proper C 309 curing method is optional if you don't care what the surface looks like, or its strength and durability. That's why silicates do not cure concrete.
What is a cure blanket?
Curing blankets allow concrete work to be done in cold climates.
Why do you need a curing blanket?
When the weather’s too cold, a curing blanket will keep temperatures where you need them. They’ll also keep moisture at the surface, help regulate evaporation and keep the concrete dry from outside water like rain or snow. Since almost all concrete blankets are water resistant they also double as a vapor barrier.
Why do electric blankets heat up?
Electric blankets have wire coils running through them that heat up when electrified. This is in additional to their insulation. When the insulation in the blanket isn’t enough to keep the concrete warm, plug in the blanket to produce more heat.
Why is a concrete blanket not needed?
In warm climates, a concrete blanket isn’t needed because the temperature required for curing is already correct. But what about here in the Northeast where it routinely gets below freezing or in states like Alaska that are almost always too cold for concrete work. Not only are the working conditions cold, but the concrete mixture itself can freeze. To prevent this from happening concrete blankets are used to cover the concrete and keep it warm.
How to keep concrete moist?
When it’s hot, masons will spray water on the concrete’s surface to keep it moist. The concrete needs to dry out, but it has to be done slowly. Rapid drying isn’t as bad as freezing but it’s still a big problem. In cold climates, you can actually have both problems happening at the same time. Many cold climates are also very dry. When water evaporates from the surface it can freeze as soon as it hits the air. So how do you keep the concrete’s surface moist? With a concrete blanket.
When to use a blanket on concrete?
These are often used in extremely cold temperatures where insulation isn’t enough. They can also be used when more heat is needed than the concrete can produce on it’s own. Don’t forget that in very cold climates, the ground is also quite cold. Since there’s no way to prevent the cold earth from touching your concrete and sapping it’s heat, you can add more to compensate for the heat loss by powering the blanket.
Can you put electric blankets on concrete?
Electric powered concrete blankets are great for this. Just lay them on the surface and plug them in, the blankets will do all the work. Next you need to figure out how much insulation is needed.
