The present invention describes various methods for manufacturing gel composite sheets using segmented fiber or foam reinforcements and gel precursors. Additionally, rigid panels manufactured from the resulting gel composites are also described. The gel composites are relatively flexible enough to be wound and when unwound, can be stretched flat and made into rigid panels using adhesives.

Provided is a structure protection sheet that allows for significant shortening of the work period required to place the protection sheet on the surface of a structure such as a concrete structure, that can protect the structure over a long period of time, and that further has excellent strength properties. The structure protection sheet is a sheet to be attached to the surface of a structure and includes, in order, a bonding layer, a polymer-cement hardened layer, and a resin layer.

An apparatus for producing a cementitious board includes a conveying device for conveying a first liner with first overlap sections-in a transport direction, at least one slurry feeder device for applying at least one layer of at least one slurry comprising a cementitious material onto the first liner, a liner feeding device for providing and arranging a second liner with second overlap sections such that it contacts the first overlap sections of the first liner wherein the at least one layer of the at least one slurry is arranged between the first liner and the second liner, an adhesive foam feeder for providing an adhesive foam on at least one of the first or the second overlap sections, and a means for bonding the first liner and the second liner.

An article has a substrate and a layer atop the substrate. The layer has: a matrix comprising at least one of hafnium silicate (HfSiO.sub.4) and ytterbium disilicate (Yb.sub.2Si.sub.2O.sub.7); and barium magnesium alumino silicate (BMAS).

The present disclosure provides a structure protection sheet comprising a polymer cement cured layer on a side facing a structure; a resin layer on the polymer cement cured layer; and a mesh layer.
