Abstract
An embodiment of a concrete curing blanket includes a top layer having a transparent material, an intermediate layer including an absorbent material and a water super-absorption polymer powder, and a bottom layer including a pervious fiber material, such as burlap. The polymer powder includes polymer chains which decompose upon exposure to sunlight. Water is absorbed in the intermediate layer and released to the bottom layer upon decomposing of the polymer chains. The bottom layer can contact the concrete surface when the blanket is positioned thereon. Water released from the intermediate layer passes through the bottom layer onto the concrete surface.
