Multifunctional cork - alkali-activated fly ash composites: A sustainable material to enhance buildings' energy and acoustic performance

This work evaluates, for the first time, the possibility of producing multifunctional alkali-activated composites combining ultra-low density, low thermal conductivity, high acoustic absorption, and good moisture buffering capacity. The composites were prepared using cork as a lightweight aggregate....
