Abstract
Shrinkage occurring in filled resinous systems prior to hardening is controlled by incorporating therein blowing agents that normally generate gas by thermal decomposition, and/or activators for such agents or calcium carbide, in the filled resinous system and causing a comparative positive volume change in the system without the application of external heat to the system and without the development of any significant exothermic heat. Thus, chemical blowing agents generate gas in the filled resinous system to effect its volume, with or without the presence of activators, although maximum exotherms recorded are far below the lowest heat decomposition requirements of the conventional blowing agents utilized and no external heat is applied. Certain known activating agents for chemical blowing agents when used alone without the blowing agent have also shown unexpected abilities to affect the volume of filled resinous systems. The additive may be blended with the fillers for the resinous material in varying amounts to achieve a reduction or elimination of shrinkage or to expand the filled system. Epoxy grouts and mortars incorporating various blowing agents with or without activators are exemplary.
