A low cost inorganic binder has recently been developed that is fabricated at room temperature by a process similar to that of concrete cement. Developed at Argonne National Laboratory (ANL), and called Ceramicrete, it has a variety of applications ranging from the stabilization of hazardous and radioactive wastes to the fabrication of value-added structural products with large volume uncontaminated wastes, such as ash, slags, plastics, wood chips, and rubber. Ceramicrete, a magnesium potassium phosphate hexahydrate, belongs to a class of materials known as chemically bonded ceramics. Ceramicrete binder also can be used to fabricate value-added structural products using large amounts of uncontaminated industrial wastes such as ash, slags, plastics, wood chips, and rubber. Fabrication of these products involves either adding the waste (e.g., slags and ash) directly to the Ceramicrete binder, or first making the Ceramicrete slurry and then adding the waste to the slurry and allowing it to solidify. If needed, pressure is used for compaction.
