Description

Powerblanket’s 3’x20’ insulated concrete blankets protect concrete pours from conditions that are too cold or too hot for optimal curing. Maintain hydration and successfully work through freezing winters and burning summers with these insulated curing blankets. Our patented design eliminates hot and cold spots by applying uniform full-coverage heat across the entire surface of the blanket. Use yours to thaw ground before pouring concrete and again after finishing for freeze protection.

3’x20’ concrete curing blankets come in two different thermal rating classes: 

  • Powerblanket – designed for any definitive heating applications, surrounded by a rugged vinyl shel, safely raises material temperatures as high as 100 F / 38 C (± 10 degrees F / 3 degrees C) and can be used in temperatures as low as -20 F
  • Powerblanket Xtreme – designed for harsh climates, surrounded by a rugged vinyl shell, safely raises material temperatures as high as 100 F / 38 C (± 10 degrees F / 3 degrees C) and can be used in temperatures as low as -20 F

All of our curing blankets come in an insulated, water-resistant design. All Powerblanket products are ETL certified to UL, CSA, and CE safety standards.

    Curing In-Place Concrete

    What is Curing?

    Curing is the maintaining of an adequate moisture content and temperature in concrete at early ages so that it can develop properties the mixture was designed to achieve. Curing begins immediately after placement and finishing so that the concrete may develop the desired strength and durability.

     

    Temperature is an important factor in proper curing since the rate of hydration and therefore, strength development is faster at a higher temperatures. Generally, concrete temperatures should be maintained above 50 degree Fahrenheit (10 degree Celsius) for an adequate rate of strength development. Further a uniform temperature should be maintained through the concrete section while it is gaining strength to avoid thermal cracking.
