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.
