ABSTRACT:
A lightweight, reinforced structural material, having low density and high flexure and compression strengths, is prepared by combining together inorganic cementitious material and organic polymer-forming material to form a mixture and forming the mixture into a slab while embedding an elongate reinforcing members which are relatively rigid in the depth dimension of the slab. Polymerization and setting of the material tensions the reinforcing members.
