    • The compositions, articles and methods described herein remain intact for sealing between and around structures that contact salt water. The compositions include: (i) a partially cross-linked polyacrylamide/partially neutralized polyacrylic acid copolymer; (ii) a smectite clay; (iii) an elastomer, e.g., butyl rubber; (iv) a polyolefin polymer or copolymer; and (v) a cationic flocculant, the compositions have exceptional and unexpected free swell and cohesiveness when in contact with high conductivity water or multivalent ion-containing-contaminated water. The articles of manufacture described herein all include a combination of (i) a partially cross-linked acrylamide/acrylate/acrylic acid copolymer; (ii) a smectite clay; (iii) an elastomer, e.g., butyl rubber; (iv) polyisobutene or polyisopropene; and (v) a cationic flocculent, and are used for waterproofing against high conductivity salt-containing water preferably when used in putty-like or paste-like consistency to fill areas between and around structures, e.g., to surround a pipe inserted in a concrete wall, or to seal between two concrete sections.
    • 本文所述的组合物,制品和方法保持完整,用于密封接触盐水的结构之间和周围。 组合物包括:(i)部分交联的聚丙烯酰胺/部分中和的聚丙烯酸共聚物; (ii)蒙皂石粘土; (iii)弹性体,例如丁基橡胶; (iv)聚烯烃聚合物或共聚物; 和(v)阳离子絮凝剂,当与高电导率水或多价离子含有污染的水接触时,该组合物具有特殊且意想不到的自由膨胀和粘结性。 本文所述的制品均包括(i)部分交联的丙烯酰胺/丙烯酸酯/丙烯酸共聚物的组合; (ii)蒙皂石粘土; (iii)弹性体,例如丁基橡胶; (iv)聚异丁烯或聚异丙烯; 和(v)阳离子絮状物,并且用于防止高导电性含盐水,优选当以油灰状或糊状稠度使用以填充结构之间和周围的区域时,例如围绕插入混凝土中的管 墙壁或两个混凝土段之间的密封。

    • Reactive gabion cage or grid structures, and their methods of manufacture, for controlling contaminants in soil, sediment or water that allow the passage of essentially non-contaminated water therethrough. The articles and methods described herein utilize gabions cages or grids, which are box shaped cages or grids (see FIG. 2) made of either steel wire mesh or plastic. In one embodiment, reactive geotextile mats are disposed on a top major surface of a gabion cage or grid. In other embodiments, the cages or grids surround a geocomposite containing reactive material. The gabion cage or grid structures can be constructed in-situ (at the site of deployment) or remotely (on land or barge) and set in place. They are typically placed side-by-side and, in a preferred embodiment, are configured to cover a target sediment area, underwater. The gabion cages or grids may be filled with clean sediment, silt, sand and/or concrete block or rock to hold the reactive geocomposite in place and for armoring.
    • 反应性格栅笼或栅格结构及其制造方法,用于控制土壤,沉积物或水中的污染物,使得基本上不受污染的水通过其中。 本文所述的制品和方法使用由钢丝网或塑料制成的盒形笼或网格(见图2)的笼形笼或网格。 在一个实施例中,反应性土工织物垫设置在石笼笼或网格的顶部主表面上。 在其他实施例中,笼子或网格围绕包含反应性材料的地质复合材料。 石笼笼或网格结构可以在现场(在部署地点)或远程(陆地或驳船)建造并设置到位。 它们通常并排设置,并且在优选实施例中,被配置为覆盖水下的目标沉积区域。 石笼笼或网格可以填充清洁的沉积物,淤泥,沙子和/或混凝土块或岩石,以将反应性地质复合材料保持在适当位置并用于铠装。
