Abstract

The invention provides a method for the encapsulation of fine particulate materials which comprises treating these materials with a microfine hydraulic inorganic filler which, typically, comprises a cementitious material, such as Portland Cement. The filler is ground to a much smaller particle size than is normally used in the production of a grout and is provided in the form of an aqueous composition for the treatment of the fine particulate materials by pumping under pressure through these materials such that they become intimately encapsulated. The method is particularly applicable to the treatment of waste materials and, most particularly, waste materials which are encountered in the nuclear industry.
