Foam Glass from Mechanoactivated Zeolite-Poor Rock

The possibility of making foam glass from zeolite-poor rock is examined. Mechanoactivation of the crushed rock or the addition of opoka rock to alkaline zeolite-containing compositions significantly increases the foaming intensity. In addition the macroand microporous structure of the foam material obtained from rock conventionally crushed in a rod mill differs from that of the foam material made from mechanically activated rock powder.
