Abstract
Curing blanket having a clear, transparent or opaque first layer and a second layer that is airlaid on the first layer. Another embodiment has a first layer, a second layer that is airlaid on the first layer, and a third layer disposed on the said second layer, with the second layer interposed between the first layer and the third layer. The first layer and said second layer are thermally bonded and/or latex bonded. The third layer includes a polymer release agent composed of bi-component fibers.
Claims21
A system for wet curing concrete, comprising:
- a curing slab of concrete having a surface;
- and
- a curing blanket disposed against the surface of curing concrete, comprising:
- a first airlaid layer consisting of a composition of binder material and natural cellulose bleached fluff pulp fiber derived from wood through Kraft processing bonded to a second layer,
- the second layer forming a vapor barrier,
- the first layer forming a wicking layer positioned between the vapor barrier and the surface of curing concrete, and
- wherein the wicking layer is operative to wick moisture from oversaturated areas to dry areas to equalize moisture saturation within the wicking layer and apply substantially uniform wetness against the surface of curing concrete.

A method for curing concrete, comprising the steps of:
- providing a curing blanket comprising an airlaid wicking layer consisting of a composition of binder material and natural cellulose bleached fluff pulp fiber derived from wood through Kraft processing bonded to a vapor barrier layer;
- wetting a surface of curing concrete;
- positioning the curing blanket on the wet surface of curing concrete with the wicking layer positioned between the vapor barrier and the surface of curing concrete;
- and
- wherein the wicking layer wicks moisture from oversaturated areas to dry areas to equalize moisture saturation within the wicking layer and apply substantially uniform wetness against the surface of curing concrete.
