Latest Patents

Tallent's latest patents include a method and composition for the immobilization of waste in cement-based materials. This invention discloses a composition and method for the fixation of aqueous hazardous waste material in cement-based materials, specifically grout. By adding an ionic aluminum compound to the waste material or the mixture of waste material and dry-solid cement-based material, the amount of drainable water in the cured grout is reduced. This innovation eliminates the need for large amounts of expensive gelling clays in grout materials, resulting in improved consistency and properties of cement-based waste disposal materials. Another significant patent involves a grout formulation for the disposal of low-level and hazardous waste streams. This invention addresses the challenge posed by fluoride in waste materials, which acts as a set retarder, preventing cement-based grouts from setting. By incorporating calcium hydroxide into the dry-solid portion of the grout mix, Tallent's invention renders fluoride insoluble, allowing the grout to set and immobilize hazardous constituents effectively.
