A concrete element with improved fire resistance having a textile reinforcement, such as carbon fibers. The concrete covers the textile reinforcement around 10 to 25 mm, the concrete being made from binding agents based on geopolymers or calcium-aluminate cements or Portland cement or blast furnace cement combined with an increased concentration of more than 2 kg/m.sup.3 polypropylene fibres and high temperature resistant aggregates. The textile reinforcement with fibers/filaments are impregnated with an impregnation mass/resin, ensuring, even at very high temperatures, a transmission of force between the fibres and the impregnation mass and protecting against the entry of oxygen. It also contains an organic faction of, for example, a maximum of 20 wt. %, wherein the impregnation masses being used, have a filler which is stable at high temperatures in an added amount of, for example, at least 12.5% in the form of particles.

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.

An arrestor bed for slowing an oncoming aircraft, including an elongated excavation, a plurality of foamed glass aggregate bodies positioned within the elongated excavation, and a covering positioned over the elongated excavation to define an arrestor bed. The respective foamed glass aggregate bodies are oblong, irregularly shaped bodies and have characteristic stacking angles of about 35 degrees. The arrestor bed has a rapid brittle crushing failure mode under compression.

The present disclosure describes modular blocks configured to give the appearance of natural or cut stone. An aesthetic coating composition may be applied to one or more surfaces of a block having a low-density, such as an insulating concrete form (ICF), to form an modular block having the appearance of cut stone. The aesthetic coating composition includes a binder component, such as a cementitious binder made from white Portland cement, or a polymer binder such as an acrylic binder, an aggregate component, such as a limestone aggregate component, and optionally an adhesive component. The aggregate component includes a fine sand portion and a coarse sand portion that effectively enable the appearance of cut stone after finishing of the aesthetic coating surface via sanding, polishing, sandblasting, acid etching, acid finishing, or exposed aggregate finishing.
