Abstract
A composition and process for the safe removal and treatment of hazardous waste material is described. This composition is a mixture of grout like cement containing the hazardous waste and a minor amount of an alkali metal silicate and a gelling agent. The hazardous waste is then safely contained within the resulting cementitious material and can be safely disposed by burial, for example. The contaminated wastes are contained within the block and will not be exposed by regular soil actions. This composition and process is particularly useful for treating soil contaminated by low level radioactive materials.

A composition for the treatment and stabilization of hazardous wastes comprising a mixture, in parts by weight, of 0 to 50 parts sand, 5 to 25 parts cement, 2.5 to 18.75 parts water, 12.5 to 75 parts of hazardous waste, and minor amounts of an alkali metal silicate and a gelling agent.
A method for the treatment and stabilization of hazardous wastes comprising the steps of adding 0 to 50 parts sand, 5 to 25 parts cement, 2.5 to 18.75 parts water, 12.5 to 75 parts of hazardous waste, and minor amounts of an alkali metal silicate and a gelling agent.
A continuous process for the treatment and stabilization of hazardous wastes comprising the steps of intimately mixing 0 to 50 parts by weight of sand, 5 to 25 parts by weight of cement, 2.5 to 18.75 parts by weight of water, 12.5 to 75 parts by weight of hazardous waste, and minor amounts of an alkali metal silicate and a gelling agent, allowing this mixture to harden wherein when said mixture is in a hardened form said hazardous waste is in a format suitable for safe disposal thereof.
