A cementitious composite for in-situ hydration includes a first layer, a second layer, a cementitious mixture including cementitious material positioned between the first layer and the second layer, and a structure layer positioned between the first layer and the second layer. The cementitious mixture comprises a majority of a volume between the first layer and the second layer.

The invention relates to a floorboard (1, 2) which has a carrier plate (3) having a top-side veneer (4), in particular a wood veneer. The carrier plate (3) and the veneer (4) are connected to each other via a resin (6). There is an edge strip (14, 15) at least on two side edges (12, 13) of the veneer (4). Said edge strip (14, 15) consists of resin (6). Carrier plate (3) and veneer (4) having the resin (6) are hot-compressed to each other. During compressing, pores, cracks, and/or gaps in the veneer (4) are filled with resin (6).

A wall panel may have a rigid layer, a first insulation layer made from a two-part rigid urethane pour foam, and a second insulation layer made from a phase change material. The first insulation layer maybe chemically bonded to the rigid layer and may also be bonded to the phase change layer. The first insulation layer may be positioned between the second insulation layer and the rigid layer. The rigid layer may be a finished surface or a veneer layer may be applied to the rigid layer.

A method of forming a coating layer on a fibrous mat to make a coated article includes depositing a coating composition on a carrier material and at least partially embedding a first major surface of a fibrous mat in the coating composition, the fibrous mat including a plurality of mat fibers. The coating composition is at least partially hardened to form a coating layer at the first major surface of the fibrous mat. A second major surface of the fibrous mat opposite the first major surface includes an uncoated portion of the plurality of mat fibers.

A spar cap for a rotor blade of a wind power installation, having a longitudinal extent from a first end to a second end, a transverse extent orthogonal to the longitudinal extent, and a thickness orthogonal to the longitudinal extent and to the transverse extent. A method for producing a spar cap as mentioned at the outset. The spar cap has a longitudinal extent from a first end to a second end, a transverse extent orthogonal to the longitudinal extent, and a thickness orthogonal to the longitudinal extent and to the transverse extent, at least two tiers of a first fiber composite material, and at least one tier of a second fiber composite material, wherein the first fiber composite material has a matrix material and/or fibers which is/are different from that/those of the second fiber composite material, the second fiber composite material is disposed in a portion adjacent to the second end, in the direction of the thickness between the at least two tiers of the first fiber composite material, and the at least one tier of the second fiber composite material terminates ahead of the second end.

Gypsum panels, methods for their manufacture, and systems and methods for monitoring environmental conditions with such panels are provided herein. The panels include a gypsum core having a first surface and an opposed second surface, a first facer material associated with the first surface of the gypsum core, and an environmental sensor assembly associated with the gypsum panel and configured to detect an environmental condition of the gypsum panel and wirelessly communicate data on the environmental condition to a reader.

A passive cathodic protection process for preservation of em bedded metallic foundations entails embedding a wrap around a metallic foundation. The wrap has an outer sheath and an inner absorbent mat to be in direct contact with the metallic foundation. The is also mat hydrophobic. The wrap is subsumed such that an upper edge of the wrap is accessible. An oil-based metallic soap is injected via the upper edge to impregnate the mat. The metallic soap is selected from a set of metallic soaps such that the metal of the metallic soap is more electropositive than the metal of the metallic foundation such that the metallic soap acts as an anodic solution for galvanic exchange with metal within the em bedded metallic foundation for the passive cathodic protection thereof. For example, zinc naphthenate may be selected for steel or aluminium foundations thereby allowing for both passive cathodic protection and biocidal action.

An impact resistant exterior sheathing gypsum building panel with an integrated impact resistant woven mesh which protects against impact from projectiles such as those conveyed by hurricane force winds is provided. Methods for manufacturing these exterior sheathing gypsum building panels with an integrated impact resistant woven mesh are also provided. An exterior sheathing system employing the exterior sheathing cementitious building panel is provided.
