Patent number: 10016954Abstract: Geocomposite articles that can provide a barrier against high conductivity water e.g., ocean water, are described and their method of manufacture, for waterproofing surfaces that contact high conductivity water. The geocomposite article mat includes a woven or non-woven geotextile sheet or mat containing a powdered or granular partially cross-linked acrylamide/acrylate/acrylic acid copolymer across its entire major surface(s). The powdered or granular copolymer has an unexpectedly high free-swell when hydrated with High Conductivity water, such as ocean water. A liquid-impermeable cover sheet is adhered to the upper major surfaces of the filled copolymer-carrying geotextile to provide a primary high conductivity water barrier layer that, if ruptured, is sealed by the swell of an underlying layer of water-insoluble, partially cross-linked acrylamide/acrylic acid copolymer.Type: GrantFiled: March 31, 2011Date of Patent: July 10, 2018Assignee: AMCOL INTERNATIONAL CORPORATIONInventors: Michael Donovan, Thomas W. Beihoffer, Nataliya V. Larionova, Marek R. Mosiewicz

Patent number: 6090734Abstract: A hydrothermal reaction which dissolves the amorphous silica and the crystalline silica impurities contained in a recovered, naturally occurring montmorillonite clay, and subsequently converts the dissolved silicas into a dioctahedral and/or trioctahedil smectite clay. The dissolution of silica is accomplished by adjusting the pH of an aqueous slurry of the recovered clay to a value of about 8.5 to about 10.0, preferably about 9.0 to about 9.5, at a temperature of at least about 150.degree. C., preferably about 180.degree. C. to about 250.degree. C., more preferably about 190.degree. C. to about 235.degree. C. Dissolved silica reacts with stoichiometric amounts of aluminum and/or magnesium and/or sodium added to the slurry, while at a temperature of at least about 150.degree. C., preferably about 185.degree. C. to about 250.degree. C.Type: GrantFiled: March 18, 1998Date of Patent: July 18, 2000Assignee: AMCOL International CorporationInventors: Semeon J. Tsipursky, Don D.
