    摘要： An appliance cabinet includes a structural envelope having an exterior surface and an interior surface that defines an insulating cavity, wherein the insulating cavity defines an at least partial vacuum. A plurality of silica-based agglomerates are disposed within the insulating cavity, wherein each agglomerate of the plurality of silica-based agglomerates includes silica-based powder insulation material that is water-densified and is at least substantially free of a material binder. A secondary insulation material is disposed within interstitial spaces defined between the plurality of silica-based agglomerates, wherein the plurality of silica-based agglomerates defines an interior structure that resists inward compressive forces exerted as a result of the at least partial vacuum defined within the insulating cavity.

    摘要： A low-density, high-strength concrete composition that is both self-compacting and lightweight, with a low weight-fraction of aggregate to total dry raw materials, and a highly-homogenous distribution of a non-absorptive and closed-cell lightweight aggregate such as glass microspheres or copolymer polymer beads or a combination thereof, and the steps of providing the composition or components. Lightweight concretes formed therefrom have low density, high strength-to-weight ratios, and high R-value. The concrete has strength similar to that ordinarily found in structural lightweight concrete but at an oven-dried density as low as 40 lbs./cu.ft. The concrete, at the density ordinarily found in structural lightweight concrete, has a higher strength and, at the strength ordinarily found in structural lightweight concrete, a lower density. Such strength-to-density ratios range approximately from above 30 cu.ft/sq.in. to above 110 cu.ft/sq.in., with a 28-day compressive strength ranging from about 3400 to 8000 psi.

    摘要： A lightweight concrete formulation containing Portland cement, aggregate, glass particles, water and metakaolin. At least 80% of the glass particles have a grain size of less than 2 mm. The glass particles contribute between 3% and 20% of the total weight of the concrete formulation. The metakaolin contributes between 4% and 12% of the total weight of the concrete formulation. The glass particles are preferably expanded glass particles. Also provided is a lightweight grout formulation containing Portland cement, glass particles, water and metakaolin. At least 80% of the glass particles have a grain size of less than 2 mm. The glass particles contribute between 3% and 15% of the total weight of the grout formulation. The metakaolin contributes between 7% and 15% of the total weight of the grout formulation.

    摘要： A method of making a foamed glass composite, including crushing a vitreous precursor material, such as waste glass, frit, metallurgical slag or the like, sizing the crushed vitreous precursor to segregate an amount of crushed particles of a predetermined size and pelletizing the crushed particles. The pellets are preheated and passed through a high-temperature flame to foam the pellets. The foamed pellets are air-quenched to a temperature below their dilatometric softening point and then cooling to room temperature. The foamed pellets are then mixed with Portland cement and water to form a composite material. The flame temperature is at least about 1300° C. and the pellets are preheated to within no more than about 25° C. of their dilatometric softening point. The pellets have a volume of between about 0.05 and about 1 cubic centimeter and reside in the flame for between about 0.5 to about 10 seconds.
