ABSTRACT:
The invention discloses an improved structural glass composition and process for manufacture. In one embodiment in which the improved structural glass may be used in isolation, the glass comprises a foamed glass core which is manufactured by supplying a glass base through which a gas is infused, either by reaction or by entrapment. As the gas to glass ratio is increased to an optimum level, the quality of the foamed glass moves from a stiff homogeneous glass which is strong in compression, weak in compression and brittle, to a foamed glass which is strong in compression, weak in tension and ductile. In a second embodiment of the invention inorganic fibers supported by a glass matrix may be wrapped around the foamed glass core. This fibrous material is generally strong in tension and also ductile. The resultant combination is a glass structure which is both strong in compression and strong in tension and which is ductile. It is anticipated that the improved glass composition may be used in place of or in combination with traditional steel, concrete, wood, aluminum or other building materials, and may provide the added benefits of lower embodied energy, better thermal and acoustical insulation and increased protection against the elements, as well as being fire resistant.
