A method of making a roadbed, including paving an area with foamed glass bodies to define a bed and covering the bed with a layer of cementitious material to define a composite bed. The composite bed is at least 85 percent foamed glass bodies. The composite bed has a cementitious surface.

Disclosed herein are composite materials, including composite building materials, comprising a polyurethane composite core in physical communication with a cementitious layer. Also disclosed are methods for producing the composite materials.

Hexagonal Boron Nitride (hBN) is a synthetic material that may be used in several applications due to its chemical inertness, thermal stability, and other beneficial properties. hBN composite materials and method for making such composites are described here. In particular composite materials including both functionalized hBN and cement or cementitious materials and methods for making the same are discussed. Such materials may be useful for construction, well cementing (both primary and remedial cementing), nuclear industry, 3D printing of advanced multifunctional composites, and refractory materials.

The present invention relates to primer compositions in powder form that comprise a dispersion powder based on an acrylate polymer having a glass transition temperature in the range from 50 C. to +30 C. and cement. The compositions of the invention are notable for good water barrier effect, good dust-binding capacity, and a low tendency toward salt efflorescence. The compositions find use in the priming of masonry, concrete, rendered surfaces, abraded render, plaster surfaces, wall blocks, wood, and ceramic tiles. They can also be used as adhesion promoters with nonabsorbent substrates such as glazed ceramic or glass tiles, metal surfaces, or surfaces of plastic.

Luminescent concrete compositions containing cement, fine aggregates such as sand, and a phosphor such as strontium aluminate. Glow-in-the-dark concrete products made therefrom and methods of producing such concrete products are also specified. The glow-in-the-dark concrete products demonstrate good mechanical strength (e.g. compressive strength) and skid resistance. The addition of phosphorescent strontium aluminate provides luminance that persists for up to 10 hours to the concrete products.
