ABSTRACT OF THE DISCLOSURE This invention relates to a method for the production of compositions showing no shrinkage or increase in their volume in course of setting which find their application in building, engineering, electrotechnical engineering and other fields of technology. The method comprises adding a special expanding system to a composition including synthetic resins or elastomers. Said system consists of an expanding agent, and expansion promoter, and if need be an expansion moderator, and sodium and/or potassium and/or magnesium fluosilicate. As the expanding agent, substances are used having a porous structure and absorption properties, such as aluminosilicates, and as the expansion promoter, substances are used having a polar structure and wherein the critical diameter of the particle is smaller than that of the pores of the expanding agents, as for instance alcohols.
