Abstract

A two-phase material of foamed cement or concrete and polymer providing tmal insulating, structural elements composed of an unimpregnated foam cement or concrete core and impregnated surface regions of the two-phase material and method employing a hydraulic head or vacuum means to provide high polymer loading through a large volume of foam voids in the cement or concrete for easy impregnation of high viscosity monomers and uncured resins to a considerable depth below the surface of the cement or concrete before in situ polymerization.
