The FluxWrap is combined with either a cooler or
chiller to achieve opmum results. The Circulaon
Blanket draws heat to the blanket in order to cool
the concrete.
• Use Powerblanket’s patented heat-spreading
technology in reverse–the cooling blanket
draws heat away and lowers the temperature of
the concrete
• Take it with you on every job: it is easily porta-
ble
• Blanket cover and insulaon are the same as
the robust system used in Powerblanket heat-
ing products
• Control the curing speed of newly poured con-
crete even in hot condions
It’s important to note that concrete can cure faster
if exposed to higher temperatures during the drying
process, but doing so can compromise its strength
and lead to cracking. The American Concrete Ins-
tute says if concrete has set properly and is not ex-
posed to harmful elements such as wet weather or
eroding chemicals, “concrete need not deteriorate.”

The same goes for hot temperatures and high hu-
midity. High temperatures mean faster curing, but
fast curing equates to weaker strength in the end.
The following study by Paul Klieger in the Portland
Cement Associaon Research Bullen 103 illus-
trates this concept.
At an age of 1 day the 120°F concrete was stron-
gest and the 25°F concrete was weakest. By 7 days
the high-temperature cured concretes had no more
strength than the 73°F concrete or even less. By
the age of 28 days the high-temperature concretes
were weaker than the 73°F concrete. From 28
days to 1 year the 55°F concrete was considerably
stronger than the 73°F concrete. All of this suggests
that, provided there is connuous curing, concrete
cured at about 55°F for the rst 28 days ulmately
reaches the highest strength.
Keeping Your Cool
If you are dealing with hot condions and your
concrete seng too quickly, consider FluxWrap.
The FluxWrap from North Slope Chillers is porta-
ble cooling equipment that will keep newly poured
concrete safe from heat, regulang concrete seng
me in both regular and hot condions.
