ABSTRACT:
The invention relates to a process for the preparation of a concentrate or starting mixture containing pigments, blowing agents or mixtures thereof, for making construction elements, which need uniform distribution wherein an aqueous suspension of a pigment and/or blowing agent containing a surfactant is combined with a plurality of ferromagnetic bodies in a rotating electromagnetic field to cause stirring of the suspension.
The resultant starting concentrate mixture may then be successfully used in making colored silica brick, various colored concretes, as well as for preparing cellular concrete which is widely used in civil engineering and industrial building by adding the proper amount of the concentrate to the raw materials for the concrete or bricks.
