Publication number: 20230090940Abstract: 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.Type: ApplicationFiled: March 4, 2021Publication date: March 23, 2023Inventors: Jessica H.

Patent number: 7850771Abstract: There are provided compositions for the preservation of wood and related cellulosic and lignocellulosic materials. The wood preservative compositions of the present invention contain an organic preservative agent and an organic acid, and can be solubilized in an organic phase essentially free of volatile organic compounds (VOC). The organic acids may serve various purposes in the compositions of the present invention: (1) increased preservative solubility in the organic phase, (2) improved distribution gradient of the active preservative in treated wood, or (3) reduction of preservative leaching.Type: GrantFiled: September 9, 2005Date of Patent: December 14, 2010Assignee: Viance, LLCInventors: Futong Cui, Alan F.

Publication number: 20080003395Abstract: One aspect of the invention is an engineered wood board. The wood board has a major face, and is made up of strips of wood which are oriented with the grain vertical relative to that major face. Additionally, the wood board contains an additive, which is present to improve the exterior durability of the wood. Another aspect of the invention is a method for manufacturing an engineered wood board that has a major face. The method includes the step of obtaining strips of wood that have a flat grain surface and a vertical grain surface. Those strips are assembled side by side, and are oriented with the vertical grain surfaces defining the major face of the board. Once the strips of wood are assembled, they are bonded together. At any stage in the method, a treatment is added to the wood to improve its water repellency and exterior durability.Type: ApplicationFiled: June 30, 2006Publication date: January 3, 2008Inventors: Futong Cui, Alan Preston, Lehong Jin, Paul Walcheski, Andrew R.

Patent number: 7264886Abstract: Water-based wax emulsions, optionally for use in conjunction with alkaline copper and/or quaternary ammonium based preservatives systems, are described. These emulsions are comprised of natural or synthetic wax, nonionic surfactants having HL B values greater than 11, anionic surfactants, and water. Certain emulsion compositions as described in this specification posses the unique property of maintaining emulsion stability in wood preservatives during extended use in typical wood treatment processes. Water-repellant wood treated with the wax emulsions are described. A method of treating wood, comprising providing wood and treating the wood with the wax emulsion under conditions effective to increase its water repellency is also disclosed.Type: GrantFiled: May 14, 2003Date of Patent: September 4, 2007Assignee: Viance, LLCInventors: Futong Cui, Alan F.

Patent number: 6274199Abstract: A process for treating a wood substrate with a water-based formulation containing a wax in order to confer water repellency to the substrate comprising the steps of: (a) placing the substrate in a treatment vessel and reducing the pressure in the vessel to remove air in the pores of the substrate; (b) contacting the substrate in the vessel, while reduced pressure is present in the vessel, with the formulation to allow the formulation to flow into said pores, said contacting being carried out at a temperature at or above that required to cause the wax to change into a molten state; (c) applying a positive pressure to the vessel to force the formulation into said pores; and (d) releasing the pressure in the vessel and removing the resultant wood substrate from the vessel.Type: GrantFiled: January 19, 1999Date of Patent: August 14, 2001Assignee: Chemical Specialties, Inc.Inventors: Alan F.

Patent number: 5698829Abstract: A process is provided herein for extracting organic toxic contaminants including pentachlorophenol, polychlorinated dibenzo-p-dioxins, and polychlorinated dibenzofurans, from wood, e.g., utility poles, fence posts, or railway ties. The process comprises extracting the wood with a supercritical fluid in conjunction with an entrainer having wood swelling properties and an agent to break the hydrogen bond between the organic toxic contaminants and the wood, at conventional supercritical fluid extraction temperatures and pressures. The process is further improved by exposing, either in a slurry of the wood phase, or in a liquid phase resulting from such extraction, the contaminants to UV, e.g., sunlight, in the presence of a photosensitizer. The present invention also provides for the photodegradation of a solution of organic toxic chemicals including pentachlorophenol, polychlorinated dibenzo-p-dioxins, and polychlorinated dibenzofurans, by exposing such solution to UV, e.g.Type: GrantFiled: September 21, 1995Date of Patent: December 16, 1997Assignee: Bell CanadaInventors: John N.
