How to wet cure concrete slabs using UltraCure NCF


Friday, May 28, 2010 / 0 Comments »

Unroll the UltraCure NCF™ wet curing blanket (plastic side up) in the widest practical width as soon as tUltraCure NCF Wet Curing Blanket Installationhe concrete surface has hardened sufficiently to prevent damage when walked on. Sides and end should be lapped at least (3) three inches. Cover the entire concrete floor surface including edges of paving and sidewalks. Immediately repair any holes or tears during curing period using wet cure material and water.

Wet the slab-on-grade surface with 1/8” to 1/4” inch of water covering the entire surface area of slab, then slowly unroll the curing blanket onto slab. Once UltraCure NCF has been put into use on a slab-on-grade or other concrete application, do not reuse. Be sure to smooth out any wrinkles or air pockets.

Keep the UltraCure NCF wet curing blanket in place on concrete slab for no more than seven (7) days. Continuous inspection for the purpose of maintaining 100% contact of the concrete surface is recommended during the curing period. Remove the UltraCure NCF curing blanket on the seventh day following initial installation.

After the concrete slab is cured, protect the surface using a protective blanket such as EZ Cover.

About UltraCure NCF Wet Curing Blanket
The patented UltraCure NCF wet curing blanket is a 7 day indoor/outdoor concrete curing blanket that employs a white vapor barrier. The blankets are manufactured in rolls, and shipped on pallets to the job site. Each pallet contains 32 rolls which are shrink-wrap protected to minimize exposure to contamination until the blanket is applied during the wet cure process. This advantage allows UltraCure to be temporally stored outside during the construction process.Properly installed UltraCure NCF on indoor slab on grade application UltraCure NCF comes in 1,600 sq. ft. rolls or 51,200 sq. ft. per pallet. Each roll will absorb 46-gallons of water.

Wet curing blankets — the best method for curing concrete


Monday, May 17, 2010 / 0 Comments »

There is no better method of achieving proper cement hydration, reducing discoloration and producing highly wear-resistant concrete floors and slabs than wet curing. The ultimate goal of any wet curing blanket is to maintain a 100% relative humidity condition on the slab surface for the entire curing period. It's easy to see why UltraCure outperforms other methods.

UltraCureNCF
Wet curing blanket for indoor, outdoor and slab-on-grade applications

Applying UltraCureNCF on an indoor concrete surfaceFeatures and benefits of UltraCureNCF

  • Full-term indoor/outdoor curing blanket (7-day curing duration)
  • Lightweight. Each 1,600 sq. ft. roll weighs approximately 50 pounds
  • Superior water retention. Each roll has the ability to absorb more than 46 gallons of water
  • Roll outs that are more even and flatter than many other wet cure methods
  • Disposable. Single-use fabric eliminates cross-contamination between slabs
  • Less material overlap. Minimal overlap (2"-5") means less waste than most other curing methods
  • UltraCureNCF meets or exceeds standard specifications related to sheet materials for concrete curing

UltraCureDOT
Concrete curing blanket for bridge, road and highway applications.

Wet curing vertical applications with UltraCureDOTFeatures and benefits of UltraCureDOT

  • Longer-term wet curing blanket (up to 14 days)
  • Lightweight. Each 800 sq. ft. roll weighs approximately 50 pounds
  • Exceptional water retention. Each UltraCureDOT roll can absorb up to 55 gallons of water—critical for long-term wet curing of concrete
  • Vapor barrier helps reduce solar heating of the concrete
  • Disposable. Single-use fabric eliminates cross-contamination between slabs
  • Less material overlap. Minimal overlap (2"-5") means less waste than most other curing methods
  • UltraCureDOT meets or exceeds standard specifications related to sheet materials for curing concrete
  • Available perforated for vertical applications such as water treatment facilities

UltraCure wet curing blankets provide thorough hydration, less discoloration and a more evenly cured slab. Unlike other blankets, which tend to dry out after three or four days, UltraCure's natural cellulose fabric provides constant hydration and maintains a 100% relative humidity condition on the concrete slab for the required curing period.Wet Curing Comparison Chart




Strength/Hardness: The longer 100% humidity is maintained during the cure, the more likely the concrete will reach its potentialstrength and hardness, and resist efflorescence.

Abrasion Resistance: The longer 100% humidity is maintained during the cure, the greater the consolidation of the cement molecules, thus increasing abrasion resistance.

Wicking/Laying Flat: Eliminating air entrapment means eliminating efflorescence, since the lime in the cement cannot react with CO2 in the air. Proper wicking assists in keeping the blanket in place during curing.

Most “Green” Product: A harder, abrasion-resistant slab lasts longer and is more sustainable. These wet curing blankets prevent water runoff into streams. And all of the UltraCure wet curing blankets are environmentally friendly as they are biodegradable.

Temperature Control: By allowing for proper hydration during the cure, thanks to these curing blankets’ superior water absorption, temperatures are minimized and controlled to meet ACI specifications.

Re-Wetting Labor: Because most blankets do not wick, or retain water, they must be rehydrated during the cure—and that incurs additional labor hours. UltraCure blankets do not require re-wetting if installed per the manufacturers recommendations.

Lowest Installed Cost: Compared to the competition, these innovative curing blankets are less costly in terms of material and, especially, labor.

Extend Slab Life: Proper wet curing can extend the “useable” life of a slab by 25%.
