While constructing Kansas City’s Christopher S. Bond Bridge, Massman Construction encountered a mid-winter dilemma. The support beam beneath the bridge, which formed the bottom of the gap in the precast concrete panels, was constantly exposed to temperatures at or below 0⁰F (-18⁰C). Massman concluded that traditional heating solutions wouldn’t work in this case. They turned to Powerblanket heated concrete blankets, which warmed up the surrounding concrete and support beam, keeping a constant temperature on the concrete.
“We didn’t have the time to wait out the winter for the temperatures to become more moderate. The Powerblanket concrete heating blankets certainly played an important role in keeping us on schedule and hot having to postpone the pour on an important Kansas City bridge.”
After calculating the savings in fuel, personnel to monitor the open flame, personnel and time to build and move enclosed shelters, and the heaters themselves, Walsh Construction realized it saved more than $5.43 for every $1.00 spent on the Powerblanket curing blankets.
■ 2.8 Times Faster—that’s how much a recent test found that Powerblanket concrete blankets outperformed standard curing blankets. That means doing jobs quicker in the winter.
■ 3,925 psi (276 kgf/cm2)—the strength of the concrete cured under the Powerblanket curing blanket during the three-day test, which took place in temperatures ranging from 22⁰F/-5⁰C to 38⁰F/3.6⁰C.
■ 2,162 psi (152 kgf/cm2)—the strength of the concrete cured under a standard curing blanket in the same test.
