A process for forming an inlay in a cured concrete structure includes forming a pocket in a preexisting concrete structure, filling the pocket with a cementitious mixture, curing the mixture in the pocket to form a cured mixture, and polishing the cured mixture in the pocket. The cementitious mixture includes a Portland cement, an admixture comprising at least one of a strengthener, a plasticizer, or an accelerator, and an aggregate.

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.

A cementitious material made from industry accepted precursor materials that will adhere to existing concrete or rock has several exploitable features beyond adhesion. The primary motivation for the invention was a self-adhering thin overlay of quality better or equal to the parent concrete floors is now possible. Structural repair of concrete is possible. There are a range of compositions and exploitable features than can be used to give the product flexibility across many concrete repair applications. This resulting material can demonstrate the low permeability and high strength closer to natural stone materials such as quartz and dolomite rocks than to concrete but intermediate compositions are technically viable as well. The material can be used for high quality precasts.

A system and method for producing a coal product from a carbon source material. The coal product may include a green carbon foam, a finished carbon foam, and/or a coal siding product. The system and method for producing a green carbon foam may involve pulverizing the carbon source material prior to processing the pulverized carbon source material to produce the green carbon foam using a float bath or an extruder. During production of the green carbon foam, the temperature of the float bath or extruder may be maintained at a temperature determined relative to the Gieseler fluidity properties of the carbon source material used.

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.
