Abstract

The present invention discloses a method for preparing the inorganic hardenable slurry and the use of same in the solidification of waste. In addition to water, the essential parts of the slurry are inorganic components including borates, cement-base powder and other additives such as magnesium oxide, gypsum and silica. The slurry is low in viscosity before solidification and flow freely, and within approximately 30 minutes after preparation the slurry becomes hardened into a highly solidified substance. The solidification of the slurry is resulted mainly from reaction of borate and the cement-base powder and to obtain a best result the weight of borates must be the same as that of the cement-base powder or even higher than the weight of the latter. The solidification mechanism differs entirely from the simple hydration reaction that brings about solidification of cement. The present invention also teaches a method for solidifying wastes with this hardenable slurry, i.e.to proceed solidification by admixing the various radioactive or non-radioactive dry and wet wastes with the hardenable slurry, or by burying waste pellets with the slurry. The solidified waste form thus obtained has a higher strength and the volume efficiency of the solidification is 2.5 to 10 times that of the conventional cement solidification. When applied to solidify low level radioactive wastes, the present method produces especiallya tremendous economic efficiency.
