    • A method of incorporating a material in a settable binder is disclosed. The binder includes a source of caustic magnesium oxide. The method involves mixing the material with the binder, either as part of a slurry or for subsequent formation into a slurry, and then adding a setting agent to the slurry. The setting agent is added to enhance setting of the binder. The material can be a hazardous waste material or components thereof. The inventors have surprisingly discovered that when the setting agent is added after mixing of the material with the binder, that a superior setting of the material in the binder can be achieved. The settable composition can comprise only a caustic magnesium oxide binder and a setting agent for the binder, as the inventors have surprisingly discovered that there is no need for any other binding agents, thus providing a simpler binder composition and method of use.
    • 公开了一种将材料掺入可固化的粘合剂中的方法。 粘合剂包括苛性氧化镁源。 该方法包括将材料与粘合剂混合,作为浆料的一部分或随后形成浆料,然后向浆料中加入固化剂。 添加固化剂以增强粘合剂的设置。 该材料可以是有害废物或其组分。 发明人惊奇地发现,当将材料与粘合剂混合后添加固化剂时,可以实现粘合剂中材料的优异设定。 本发明人惊奇地发现,不需要任何其它粘合剂,因此可提供更简单的粘合剂组合物和使用方法,可固化组合物可仅包含苛性氧化镁粘合剂和粘合剂固化剂。
