Abstract
Disclosed are concrete curing blankets having two or more channels. The channels extend longitudinally and are formed by fluid-tight seals, where all of the layers of the blanket are bonded together. The concrete curing blankets are placed over poured and curing concrete to maintain high water content in the concrete during curing and to accelerate the concrete curing and hardening processes.
Claims11
A concrete curing blanket comprising:
- a contact layer for contact with a concrete surface;
- a cover layer including a liquid and/or vapor impermeable polymer material for maintaining liquid and/or vapor in the blanket and preventing liquid and/or vapor leakage into the atmosphere;
- a storage layer for storing liquid, the storage layer intermediate the contact layer and the cover layer;
- and,
- the contact layer, the storage layer, and the cover layer joined together along a plurality of longitudinally extending seams, the seams dividing the blanket into at least two channels between adjacent ones of the seams, each the at least two channels including a space between the storage layer and the cover layer to maintain vapor from the storage layer;
- wherein the seams which join the contact layer, the storage layer and the cover layer, together, proximate to the ends of blanket, operate to prevent liquid and/or vapor leakage from the concrete surface into the atmosphere and maintain saturation of the concrete surface.

A method for curing concrete comprising:
- providing a concrete curing blanket comprising:
- a contact layer for contact with a concrete surface;
- a cover layer including a liquid and/or vapor impermeable polymer material for maintaining liquid and/or vapor in the blanket and preventing liquid and/or vapor leakage into the atmosphere;
- a storage layer for storing liquid, the storage layer intermediate the contact layer and the cover layer;
- and,
- the contact layer, the storage layer, and the cover layer joined together along a plurality of longitudinally extending seams, the seams dividing the blanket into at least two channels between adjacent ones of the seams, each the at least two channels including a space between the storage layer and the cover layer to maintain vapor from the storage layer;
- wherein the seams which join the contact layer, the storage layer and the cover layer, together, proximate to the ends of blanket, operate to prevent liquid and/or vapor leakage from the concrete surface into the atmosphere and maintain saturation of the concrete surface;
- and
- placing the concrete curing blanket over curing concrete including the concrete surface to maintain the liquid and/or vapor in the curing concrete.

- a cover layer including a liquid and/or vapor impermeable polymer material for maintaining liquid and/or vapor in the blanket and preventing liquid and/or vapor leakage into the atmosphere;
- a storage layer for storing liquid, the storage layer intermediate the contact layer and the cover layer;
- and,
- the contact layer, the storage layer, and the cover layer joined together along a plurality of longitudinally extending seams, each of the seams:
- 1) liquid and/or vapor tight, 2) extending in a longitudinal direction, and 3) arranged substantially parallel to each other to divide the blanket into at least two channels between adjacent seams;
- and
- wherein the contact layer, the storage layer and the cover layer are joined together by the plurality of the seams to prevent liquid and/or vapor leakage from the concrete surface into the atmosphere and maintain saturation of the concrete surface.
