Publication number: 20230228085Abstract: Fabric reinforcement for reinforcing alkaline cementitious matrix including warp yarns and weft yarns. To increase cohesive tensile strength of intersection points of the fabric the fabric has sufficient resinous coating over a substantial portion of the warp and weft yarns, before the fabric reinforcement is embedded within, or adhesively or mechanically bonded to the cementitious matrix, wherein the coating includes organic or inorganic adhesives/polymers, or the fabric has uncoated fabric modified by adhering fabric strands together where machine direction and cross-machine strands intersect, for example with cyanoacrylate or epoxy. Bond strength of the intersecting yarns of the fabric and the corresponding mechanical bond strength of the fabric to the cementitious matrix may also be enhanced by increasing roughness and/or surface area of the yarns and resulting fabric. Methods for making fabric, cementitious boards employing the fabric, and methods for making the cementitious board are also provided.Type: ApplicationFiled: September 30, 2022Publication date: July 20, 2023Inventors: David R. Blackburn, Jeffrey W. Donelan, Ashish Dubey, Christopher B. Tesmer, James B. O'Sullivan

Publication number: 20210299654Abstract: Transport of a vaporizable liquid containing at least one solute through a material containing nanochannels is performed by contacting material with at least one vaporizable liquid component and inducing liquid transport along nanochannel interior wall surfaces, wherein the material contains nanochannels having an average diameter up to about 300 nm, preferably up to about 100 nm, and liquid transport is induced by partial liquid vaporization. A film of solid material is deposited onto an interior nanochannel wall surface by removing the transport liquid.Type: ApplicationFiled: June 10, 2021Publication date: September 30, 2021Inventors: Sankar SAMBASIVAN, Francis Richard CHAPMAN, Jeffrey W. DONELAN, Christopher J. GARCIA

Hydrophobic finish compositions with extended flow time retention and building products made thereof
Patent number: 10399898Abstract: Disclosed are hydrophobic finish compositions and cementitious articles made with the hydrophobic finish compositions. In some embodiments, the article is a waterproof gypsum panel surface reinforced with inorganic mineral fibers that face a flexible and hydrophobic cementitious finish possessing beneficial waterproofing properties. These waterproof gypsum panels have many uses, such as, tile backer board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, interior wall and ceiling, and roof cover board having water durability and low surface absorption. The flexible and hydrophobic cementitious finish can include fly ash, film-forming polymer, preferably silane compound (e.g., alkyl alkoxysilane), an extended flow time retention agent including either one or more carboxylic acids, salts of carboxylic acids, or mixtures thereof, and other optional additives.Type: GrantFiled: March 10, 2016Date of Patent: September 3, 2019Assignee: UNITED STATES GYPSUM COMPANYInventors: Yanfei Peng, Ashish Dubey, David R.
