ABSTRACT:
A heating apparatus for assisting in the curing of concrete includes a heater and pump for providing a supply of heated fluid to a network of tubing arranged on the back or non-working side of a concrete form. The heated fluid is used to maintain a desired temperature of the curing concrete to reduce the cure time and/or accelerate the strength gain of the curing concrete. In an alternative embodiment, a heated concrete blanket includes a flexible sheet material on the back side of which is arranged a network of tubing through which heated fluid is distributed. The flexible blanket is used to cover curing concrete and regulate the temperature adjacent to the curing concrete. In both embodiments, insulating material may be used to cover the network of tubing on the back side of the apparatus to prevent undesired heat loss.
