Abstract
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.
