STRONG, HIGH DENSITY FOAM GLASS TILE HAVING A SMALL PORE SIZE

摘要

A strong, high density foam glass tile having a small pore size which can beused as a facade on both exterior and interior building walls. The foam glasstile of the present invention is strong enough that it can also be used as astructural member for a building. The foam glass tiles are very strong, andhave a compression strength of 6000 psi (lb./sq. in) or greater, and moreparticularly of 8000 lb./sq. in. or greater, and even more particularly of10,000 lb./sq. in. or greater, and even more particularly of 12,000 lb./sq.in. or greater, and even more particularly of 14,000 lb./sq. in. or greater.These foam glass tiles will absorb more energy from an explosion, withstandhigher heat and wind loading and other mechanical forces. The tiles of thepresent invention may have an average pore size of 1.0 mm or less, andpreferably .7 mm or less, and more preferably .6 mm or less, and even morepreferably .5 mm or less, and even more preferably .4 mm or less, and evenmore preferably .3 mm or less. The density of the foam glass tile of thepresent invention is increased from the commercially recommended density of9.5 lb./cu. ft. to have a higher density of between 30-100 lb./cu. ft., andmore particularly greater than 40 lb./cu. ft., and even more particularlygreater than 50 lb./cu. ft., and even more particularly greater than 60lb./cu. ft. The weight of the foam glass tile of the present invention is over10 lbs., and more particularly over 20 lbs., and even more particularly over30 lbs., and more particularly 35 lbs. or greater, and even more particularly40 lbs. or greater, and even more particularly 50 lbs. or greater, and evenmore particularly 65 lbs. or greater, and even more particularly 100 lbs. orgreater. The title of the present invention may also have a closed porestructure.
