Composite panels and methods of preparation are described herein. In some embodiments, the composite panel can include a first fiber reinforcement, a polyurethane composite having a first surface and a second surface opposite the first surface, wherein the first surface is in contact with the first fiber reinforcement; and a cementitious material adjacent the first fiber reinforce-opposite the polyurethane composite. The polyurethane composite can be formed from (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, (ii) one or more polyols, and (iii) a particulate filler. The fiber reinforcement can be formed from a woven or non-woven material, such as glass fibers. The composite panel can further include a material, such as a second fiber reinforcement and a cementitious layer, in contact with the second surface of the polyurethane composite. Articles comprising the composite panels are also disclosed.

A cementitious composite for in-situ hydration includes a structure layer having a first side and an opposing second side, a cementitious material disposed within the structure layer, a sealing layer disposed along and coupled to the first side of the structure layer, and a containment layer disposed along the opposing second side of the structure layer. The structure layer has an intersection at the sealing layer and the containment layer that is at least partially fiberless. The cementitious material includes a plurality of cementitious particles. The containment layer is configured to prevent the plurality of cementitious particles from migrating out of the structure layer.

A method for establishing a runway safety area adjacent a runway, wherein the runway safety area is a cement matrix having a plurality of foamed glass aggregate bodies suspended therein, including mixing cement and foamed glass aggregate bodies to define a composite material, forming the composite material into a runway safety area defining a plurality of foamed glass aggregate bodies suspended in a cement matrix, taxiing an aircraft over the runway safety area and crushing at least a portion of the runway safety area with the aircraft to bleed off the aircraft's kinetic energy, wherein the runway safety area has a crushing failure mode.

A method for manufacturing a layered tile comprising a mutually connected ceramic tile and a concrete body, the method comprising the steps of applying an organic primer to a first surface of the ceramic tile, optionally positioning the ceramic tile in a mold, exposing the first surface, applying a concrete mixture on top of the tile's first surface, pre-hardening the concrete mixture for obtaining a green product, removing the product from the mold, and fully hardening the concrete for obtaining the layered tile.

A base material for a membrane filter contains 90% by mass or more of aluminum oxide and 0.1% by mass or more and 10% by mass or less of titanium oxide. In a pore distribution curve measured by a mercury porosimeter, the base material has a first peak and a second peak which is higher than the first peak and is located at a pore size larger than that of the first peak, and the volume of pores with a pore size of 7 m or more is 0.02 cm.sup.3/g or more.

Embodiments of a system and a method for manufacturing a cementitious panel can be used to produce a cementitious panel having a multi-layer air/water barrier membrane assembly. The layers of the membrane can be built up via a series of applicator stations applying a fluid composition using roll coating, for example. Between applicator stations the applied layer of fluid composition can be subjected to drying conditions via infrared heating. To help protect from the deleterious effects of infrared heating, the cementitious panel can be conveyed through a cooling tunnel after each drying section.
