摘要： A shaped, water-expandable water-sealing article used for sealing an area between a first section of at least partially cured concrete and a second, adjacent section of substantially uncured concrete. The clay water sealing article is in the shape of a quadrilateral, preferably a trapezoid, and is disposed to bridge an area between the two sections of concrete. Upon hydration of the clay contained within the shaped water sealing article, expansion of the clay creates expansion forces extending from a corner of the article that is surrounded by the uncured concrete, wherein the corner has an included angle greater than 90.degree., preferably at least 100.degree.. The expansion force developed by the expansion of the shaped water sealing article are absorbed by a substantially increased area of the uncured concrete as compared to expansion forces resulting from a clay-based water seal having a 90.degree. included angle at the corner(s) surrounded by the uncured concrete.
摘要翻译：一种用于密封至少部分固化的混凝土的第一部分和基本上未固化的混凝土的第二相邻部分之间的区域的成形的水膨胀的水封制品。粘土水封制品为四边形，最好是梯形，并设置成桥接两段混凝土之间的区域。在成型水封制品中包含的粘土水合时，粘土的膨胀产生从被未固化混凝土包围的制品的角落延伸的膨胀力，其中角部具有大于90°的夹角，优选至少 100°。与成形水密封制品的膨胀形成的膨胀力相比，由在包围的角落处具有90°夹角的粘土基水封所产生的膨胀力相比，未固化混凝土的面积大大增加而被吸收。由未固化的混凝土。
