The invention relates to a method of impregnation of foam cements, mortars and concretes with liquid monomers and resins, subsequent in situ polymerization of the liquid monomers or resins and thermal insulating structural elements, produced by the method, comprised of composite building components having an unimpregnated core and impregnated surface regions. The production method utilizes the flow under a hydraulic gradient or vacuum means of a liquid through an interconnected gaseous phase due to foam voids dispersed within the cement paste matrix. The gaseous phase is dispersed within the cement paste before the paste hardens,and is not water filled. Subsequent polymerization of the liquid in the dispersed void system results in a two-phase material with a large volume of polymer and having optimum thermal insulating and structural properties.
