Case Study

The unheated Powerblanket® section cured 1.3 times faster than
the area under the standard blanket. When this rate of strength
gain is projected over time, the unheated Powerblanket section
will attain “design strength” (4000psi) in only 5
3⁄4
days. (This is
determined by dividing the actual age at which design strength
is attained in the laboratory by the “equivalent age-to-actual age
ratio” at the moment. For this mix design, that is assumed to be
7.5 days based on historical data.) A similar determination can be
made for all curing environments.

Unheated Powerblanket
The standard blanket is compared to the other sections, but it can
also be compared to test cylinders. In this case, the area under the
standard blanket will reach 4000psi in 8.3 days, or more than 2
1⁄2
days longer than the concrete under the unheated Powerblanket.
Considering that zero energy was expended to attain this
advantage, this should be a significant benefit to the contractor.
