ABSTRACT:
A composition and method for fixation or immobilization of aqueous hazardous waste material in cement-based materials (grout) is disclosed. The amount of drainable water in the cured grout is reduced by the addition of an ionic aluminum compound to either the waste material or the mixture of waste material and dry-solid cement-based material. This reduction in drainable water in the cured grout obviates the need for large, expensive amounts of geling clays in grout materials and also results in improved consistency and properties of these cement-based waste disposal materials.
