Large high density foam glass tile

摘要

A composite building material comprising:
(a) a foam glass tile having a density between 320.3293 kg/m³ (20 lb./cu. ft.) and 1601.8463 kg/m³ (100 lb./cu. ft.) ;
and
(b) a rigid structure,
whereby said tile is backed by said rigid structure so that if subjected to blast shock waves having blast energy, said tile can absorb a substantial portion of said blast energy to which said tile is exposed.
