Abstract
A fiber-reinforced cellular concrete is disclosed along with methods of production of the concrete material and of building materials formed from the concrete. The invention includes diverse fractions of concrete, a relatively dense, waterproofed fraction and a lightweight fraction having essentially the same composition but with gas bubbles dispersed therethrough. A composite product is formed from the casting of the lighter fraction over the heavier fraction to form a single sheet, with the lighter fractions of separate sheets being planed and bonded together with a vapor barrier therebetween to form blocks, wall panels, beams, and the like.
