摘要： Shaped geopolymeric particles, fibers, and articles incorporating at least one geopolymer are provided; the geopolymeric particles, fibers, and articles having a structure that is solid, foamed, hollow or with one or more voids. Geopolymers are formed by alkali activation of an aluminosilicate and/or aluminophosphate material. The end-products are shaped as spheres, flakes, fibers, aggregates thereof or articles. Such products are formed at low temperatures; wherein forming includes processing using techniques such as spray drying, melt spinning, or blowing. The shaped geopolymeric particles and fibers have high chemical durability, high mechanical strength, application-targeted flowability and packing properties, and are specially suited for incorporating into composite materials, articles, and for use in cementitious, polymeric, paint, printing, adhesion and coating applications. Shaped geopolymeric particles, fibers and articles having voids, hollow or foam-like structures are formed by adding one or more blowing agents.

摘要： A multi-function composition for incorporation into settable composite materials is provided. The composition is formulated as an additive to modify the density of the composite material and increase the rate of hardening or strength development of the material. The composition of the additive generally includes an alkaline activation compound such as sodium silicate and a modified low density siliceous material having at least one region morphologically altered by a chemical, such as a partially digested region. The additive can be in slurry form, in powder form, or in an agglomerated particle form. The additive can be produced using a two-stage process in which a siliceous material is reduced in particle size, combined with an alkali compound in a solution and then digested in an atmospheric or pressurized vessel. In some implementations, the solution can be spray dried to form agglomerated particles containing the alkaline activation compound and the low density siliceous particle having one or more partially digested regions.

摘要： A bottom-up cocurrent combustion furnace for the production of synthetic microspheres by thermal expansion of glass particles is provided having improved characteristics with regard to anti-fouling, process efficiency, and yield. The disclosed furnace uses preheated combustion air to preheat the feed material and to convey the feed material in a dilute phase transport regime to a burner. The combustion air, fuel, and feed material are premixed prior to being injected though the burner. The feed material rapidly expands as it is ejected through the burner and through a flame and then rapidly cools to solidify the microspheres. Additional features are provided to prevent the furnace from fouling by keeping the feed material away from the furnace walls, removing feed material that adheres to the furnace walls, and collecting feed material that agglomerates or does not expand.
