What is Powerblanket?

Powerblanket is a revolutionary new heat spreading technology that utilizes electricity and patented materials to warm concrete evenly during the curing process, resulting in a rock-hard, crack-free finish. For use in both warm and cold weather climates to protect concrete from rapid drying, freezing and cracking. Powerblanket helps retain moisture in wet curing and brings it to the desired PSI quickly and efficiently. PowerBlanket electric concrete curing blankets can achieve a compressive strength in concrete of 4300 psi in only 9 hours with no cracking or defects.

The net result is a better finish and higher quality product for the customer.

 

What does "concrete curing" mean?

Great care must be taken while curing concrete to ensure maximum concrete strength and durability. It's one of the most important steps in concrete construction! Concrete hardens when hydration (the chemical reaction between cement and water) takes place. It is therefore important that fresh concrete stay within a specific temperature range during the concrete curing process in order for hydration to occur during the 5-7 days that follow pouring.

Does temperature have an effect on new concrete?

Absolutely! If the outside temperature is too high, water used in hydration will evaporate and cause the concrete to lose constitution. On the other hand, extremely cold weather will bring the process to a halt because the water will not be reacting with the cement. The general rule of thumb is that new concrete should be maintained above 52 degrees (11 degrees celcius) for the entire curing process.

Why does concrete crack?

Just like any other substance, concrete expands when it dries out. If the drying takes place too quickly or under excessive heat, the structural integrity of the compound will be comrpomised.  It is for this reason that contractors put spaces between slabs of concrete allowing for the natural expansion. On the other hand, cold weather can also result in cracked concrete. By using Powerblanket, you maintain optimum PSI levels in concrete while it cures, eliminating many of these problems.
