摘要:
A method of treating a surface to remove unwanted material therefrom, including providing a foamed glass article formed from a starting mixture including glass, a carbonate foaming agent, and a devitrification agent selected from the group potassium phosphate, potassium phosphate tribasic, sodium phosphate and combinations thereof, and contacting the surface with the foamed glass article while providing relative movement between the surface and the article. The crystal silica content of the foamed glass body is less than 1 weight percent. The surface is treated by sanding, rubbing, scraping, degreasing, polishing, cleaning, smoothing, depilling, grooming, stripping, degumming, and combinations thereof. The surface is selected from the group comprising wood, metal, plastic, fiberglass, porcelain, glass, enameled surfaces, ceramic, concrete, or tile, and belongs to a member of the group comprising pools, spas, griddles, grills, fryers, bottles, glassware, cement pieces, marble, granite, monuments, skin, animal hides, textiles, garments.
摘要:
A method of slowing an aircraft overrunning a runway, including paving an area immediately beyond the end of a runway with foamed glass bodies to define a bed, covering the bed with a layer of cementitious material to define a composite bed, and crushing at least a portion of the composite bed with an oncoming aircraft, wherein crushing the at least a portion of the composite bed removes kinetic energy from the oncoming aircraft to slow the oncoming aircraft. The composite bed is generally resistant to fire.
摘要:
A foamed glass plant growth support structure, including a foamed glass substrate and a plurality of interconnected pores distributed throughout the substrate. The substrate is characterized by a porosity of at least about 80 percent. The pore size is substantially between about 0.2 and about 5 millimeters and the substrate is sufficiently chemically stable such that water filling the plurality of interconnected pores experiences a pH shift of less than 0.5.
摘要:
A method of making a foamed glass body, including preparing an admixture of powdered glass, at least one carbonate based foaming agent, and at least devitrification inhibitor, heating the admixture to a first temperature to soften the glass, heating the admixture to a second, higher temperature to foam the softened glass into a foamed glass body, and cooling the foamed glass body. The crystal silica content of the so-formed foamed glass body is less than 1 weight percent.

摘要:
An arrestor bed for slowing an oncoming aircraft, including an elongated excavation, a plurality of foamed glass aggregate bodies positioned within the elongated excavation, and a covering positioned over the elongated excavation to define an arrestor bed. The respective foamed glass aggregate bodies are oblong, irregularly shaped bodies and have characteristic stacking angles of about 35 degrees. The arrestor bed has a rapid brittle crushing failure mode under compression.
摘要:
A method of disposing of waste material in a waste stream, including positioning a porous foamed glass member characterized by an open-cell interconnected pore network in contact with a volume of liquid to be purified and removing an amount of an undesired material from the volume of liquid.

摘要:
A porous glass plant growth support structure, including a porous glass substrate and a plurality of interconnected pores distributed throughout the substrate. The substrate is typically formed from foamed glass and/or fused glass spheres and is characterized by a porosity of at least about 80 percent. The pore size is substantially between about 0.2 and about 5 millimeters and the substrate is sufficiently chemically stable such that water filling the plurality of interconnected pores experiences a pH shift of less than 0.5.
