Abstract: A method of this disclosure directionally drills at least one well extending from ground surface to an interior of an underground mine located below ground, the well being at an oblique angle relative to vertical; blends or mixes together a hazardous material, like lead, zinc, arsenic, and cadmium with cement including a plasticizer; pumps or flows the mixture into the well, wherein the mixture flows toward a lower end of the mine and hardens in place. The method allows for the permanent placement of contaminated mixtures like chat into mines or shafts or depositories, as defined by the United States Environmental Protection Agency, CERCLA and Superfund laws and complies with rules for the permanent closing of these structures with contaminated material and contaminated substances.

Abstract: A method for stabilizing a neutralization slag of uranium associated zirconium and zirconia, and a stabilization agent used therein are disclosed. The stabilization agent includes the following components in parts by weight: a pretreatment agent of 2-8 parts, anhydrous calcium chloride of 2-6 parts, an adsorbent of 3-5 parts and a stabilizer of 4-9 parts. The stabilization agent is used to stabilize the uranium that is existed in the neutralization slag in a waste slag. The method includes the following steps: the pretreatment agent is used to alkalize and disperse the neutralization slag; soluble calcium salt is added to cement the neutralization slag; and the adsorbent and the stabilizer are used as a composite material to passivate the neutralization slag. The method has low cost, fast effectiveness, simple process, easy operation, and long-term stable remediation efficiency, which can be applied to the treatment and disposal of associated radioactive waste residues.

Abstract: A brick fabricated from a waste fiber-reinforced polymer (FRP) includes a main body. The main body is formed of a composite. The composition of the composite includes, in parts by weight, 1.0 part by weight of a plurality of furnace slag powders, 0.35 to 0.5 parts by weight of a plurality of glass fiber/polymer particles, 0.02 to 0.5 parts by weight of a plurality of glass powders, and 0.65 to 0.75 parts by weight of an alkali solution. The glass fibers/polymer particles are obtained by crushing the waste FRP. The glass powders are obtained by crushing a waste glass. The furnace slag powders, the glass fiber/polymer particles, the glass powders and the alkali solution are uniformly mixed into a mixture. The mixture is poured into a mold, and then generates a polymerization reaction to form the main body.
