Placing concrete in cold weather creates costly effects on the integrity of the concrete if precautions are not taken to provide winter protection. Both ACI 306 and the NRMCA address the need to provide a heating solution when placing concrete in “cold weather.”
Typical problems experienced in cold weather concreting include:
- Standard insulating blankets, regardless of “R” value, do not generate heat and have limited sustainable value when it comes to retaining the heat of hydration generated by the concrete naturally.
- Force air heaters and accelerators can enhance premature curing causing possible shrinkage, a condition that can result in cracking and structural damage both short-term and long-term.
- Freezing of the bleed water necessary during the curing process.
How would your business increase if you used heated concrete blankets?
- PSI ratings achieved could be achieved 2.5 times faster than conventional curing methods and accelerators.
- You could speed up your concrete production cycles.
- Because your concrete integrity and strength increased, you could move on to other jobs.
Powerblanket heated concrete blankets not only generate and evenly distribute heat but retain that heat over longer periods of time allowing the concrete to avoid detrimental freeze-thaw effects during early stages of the curing process, an event that can greatly reduce the integrity of the concrete by as much as +/– 40 percent.
