    Abstract: A cyclone includes a cylindrical housing and has an inner diameter D. An inlet is near a first end of the housing. A deflection member can be positioned within the first end or the second end of the housing, depending on whether the cyclone is uniflow or reverse flow. An outlet tube is positioned within and extends from a second end or the first end of the housing (depending on whether uniflow or reverse flow). A bunker is formed between the outlet tube and an inner wall of the housing in a uniflow design and between the deflection member and the housing in a reverse flow design, and collects particles separated from an inlet gas stream. A gap between the deflection member and the outlet tube has a length in the range of approximately 0.4*D to 0.8*D. The length of the bunker is approximately greater than or equal to 1.5*D.

    Abstract: A light weight geopolymer concrete, having a specific gravity less than 2.0, more typically between 1 and 1.3, is provided that has compressive strength comparable to or greater than ordinary Portland concrete. The light weight geopolymer concrete has low shrinkage, expansion, and cracking, and substantially no loss of compressive strength when exposed to high temperatures of 800° C. or greater, as would occur in a fire. To be useful as a load bearing member for general applications, such as residential housing, the compressive strength of the light-weight geopolymer concrete should be at least 10 MPa, preferably greater than 12 MPa, for example greater than 15 MPa. For more demanding uses, the compressive strength should be near or at the compressive strength of concrete, that is, greater than 20 MPa, preferably greater than 30 MPa, and optimally greater than 35 MPa. To be useful during and after a fire, the strength must not be reduced by more than 20%, preferably not less than 10%, optimally not reduced at all when exposed to heat up to 800° C. Embodiments of the invention include low-density high-temperature-resistant geopolymer concrete which increases load bearing strength when exposed to temperatures above 400° C., preferably at 800° C. Key constituents for forming most embodiments include a geopolymer source such as fly ash, a cement-coated expanded vermiculite, a fiber such as wollastonite, and soluble silicates such as alkali silicates.
