Embodiments of the present disclosure generally relate to methods and materials for fabricating building materials and other components from coal. More specifically, embodiments of the present disclosure relate to materials and other components, such as char clay plaster, char brick, and foam glass fabricated from coal, and to methods of forming such materials. In an embodiment is provided a building material fabrication method. The method includes mixing an organic solvent with coal, under solvent extraction conditions, to form a coal extraction residue, and heating the coal extraction residue under pyrolysis conditions to form a pyrolysis char, the pyrolysis conditions comprising a temperature greater than about 500 C. The method further includes mixing the pyrolysis char with water and with one or more of clay, cement, or sand to create a mixture, and molding and curing the mixture to form a building material. Pyrolysis char-containing materials are also disclosed.

The invention relates to radiation-treated reinforcement fibers, reinforced asphalt and portland cement concrete, and grout, methods for producing the same and application for their use. The radiation treatment includes exposing reinforcement fibers to electromagnetic energy, e.g., gamma rays, and/or electron-beam (E-beam) radiation. As a result of the treatment, the radiation-treated reinforcement fibers have a modified or deformed surface, e.g., an abraded and/or porous surface, as compared to reinforcement fibers without a radiation treatment.

In a process for manufacturing a catalytic converter component, a ceramic unit is used that has been prepared by extruding green ceramic product through a die to form an extrusion having a honeycomb substrate structure in which tubular passages extend along the extrusion, the passages bounded by walls dividing adjacent passages from one another. The unit is obtained by cutting off a length of the extrusion and curing and firing it. The process further comprises, following the firing, injecting a mixture of a mastic component and a particulate metal component from an end of the ceramic unit into selected ones of the cells so as to block the selected cells over at least a part of the lengths thereof while maintaining all of the walls of the ceramic unit, and curing the injected material to render the injected material solid.
