The Powerblanket, concrete
curing blankets cure concrete to the ACI cold weather concreting
specifications (306).Section 3.3 states, "Prevent concrete from drying
during the required curing period". When heated enclosures are used to
cure concrete, precautions need to be taken to prevent rapid drying.
When accelerants are used, precautions need to be taken to prevent the
concrete from hydrating too quickly. Gas type heaters create a fire risk
and can leave a damaging film on the concrete's surface. When using
insulating tarps, you're relying on the heat of hydration to prevent the
concrete from freezing. Insulating tarps also trap bleeding water in
between the tarp and the concrete surface leaving an unwanted
efflorescence embedded in the concrete surface. This makes pouring
colored concrete nearly impossible in cold weather.
The Powerblanket's innovated
heat spreading technology spreads heat evenly. They retain the moisture
in curing concrete acting as a wet cure. This prevents rapid drying,
even when high amounts of accelerants are used. This eliminates cracks
and defects. Powerblanket curing blankets maintain optimal concrete
curing temperatures. These temperatures are needed in order to achieve
an accelerated strength. This reduces the number of days required to
protect concrete against freezing.
Accelerate your construction
schedules all winter long. Protect and cure your concrete the way it is
suppose to be done! Only with the Powerblanket!
