materials [24]. Perlite is an aluminium silicate that contains 72–76% SiO2, 11–13% Al2O3 and 2–5% water. When subjected to 900 C flame shock, it loses its water and expands up to 7–12 times the grain volume as a result of the explosion, turning into a low-density, porous, light material. This material is called expanded perlite (EP) [25].Web
