Architecture graduate student Tayana Ghosh has developed a new building material that combines mycelium fungus with glass. To understand the potential of this material, she has also conducted a series of compression tests.
She believes that a mycelium-glass composite could serve as an environmentally friendly material in built environments, as it requires less energy to manufacture than conventional building materials. To test this hypothesis, Ghosh’s research combines mycelium, a filiment fungus, with recycled fire-glass to make a composite brick unit.
“Mycelium is a natural adhesive material consisting of the vegetative part of a fungus,” Ghosh described. “Mycelium is a living organism and grows at room temperature, feeding on natural local feedstocks.” These feedstocks include dust and agricultural wastes such as wheat husks, corn stalks and more.
Mycelium do not require extra energy to perform the chemical reactions necessary to form a fibrous hardened block. Ghosh says that, “Nature shows time and again that everything around us happens at normal temperatures and does not need extra energy.”
Ghosh said this work is significant because “We face challenges everyday due to global warming and fast depletion of natural resources and fossil fuels.”
Ghosh’s research shows potential for the mycelium-glass material to be used for insulation boards or sandwich panels, instead of foams. As next steps, she recommends additional testing of the material, including its fire resistance and shear strength.
Ghosh is advised by Prof. Lee Fithian, with support from Profs. Marjorie Callahan and Shideh Shadravan, from the Division of Architecture. Her work was completed in the Christopher C. Gibbs College of Architecture’s Creating_Making Lab and the Gallogly College of Engineering’s Fears Lab at the University of Oklahoma.
