초록 ▼

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.

대표청구항 ▼

A method of forming a concrete building material which includes at least two separate and substantially identical sheet members of concrete secured against one another in sandwich form, comprising the steps of: (a) forming a first layer of relatively dense concrete having fibers mixed therethrough; (b) forming a second layer of a relatively lightweight concrete over said first layer prior to curing of said first layer, said second layer also including fibers mixed therethrough, said fibers in said first and second layers becoming intermingled at the interface of said layers, and said second layer including gas bubbles dispersed therethrough; (c) allowing said concrete layers to cure into sheet form and cutting said sheets to a desired length for forming distinct concrete sheet members; (d) planing the outer surface of said second layer of two substantially identical concrete sheet members for smoothing the outer surface thereof and opening said gas bubbles disposed near said outer surface; (e) applying a resinous means to the planed surfaces of said second layer; and (f) disposing one of said separate and substantially identical sheet members of concrete over said resinous means, mating opposed and planed second layers and forcing said resinous material into said open gas bubbles for creating ball and socket joints between said separate and substantially identical sheet members, said resinous material also forming a vapor barrier between said mated sheet members.
