Features & Benefits:

	Premature form stripping in cold weather can be avoided. Excessive summer heat exposure is controlled. Loading, prestressing or post tensioning as well as lifting and/or form removal can be done safely.
	Large difference in concrete strength caused by variations in temperature during curing, can be eliminated and uniformity of concrete strength achieved. Maturing concrete strength can be monitored continuously, and documented.
	Optimum scheduling of form removal, prestressing, post tensioning and highway loading achieved. Artificial heating or cooling minimized. Rework due to concrete not being cured to specified strength reduced. Costly cylinder testing reduced.
