Abstract: A studless wall system and method of erecting the same, incorporating a plurality of spaced apart reinforced wall panels forming a wall assembly. The wall panels are each made from easily handled composite beams or posts arranged in side-by-side fashion and secured to spacer members extending beyond adjacent ones of the beams. At least some of the spacer members are immobilized and the space between wall panels serves as an insulating space, or may have electrical wiring, plumbing, lighting fixtures, and heating conduits placed therein. The composite beams or posts comprise elongate steel channels filled with a suitable, lightweight cementitious material. The steel surfaces of the channels are positioned to be inside the wall assembly where they will effectively serve as a fire barrier.

Abstract: A building material prepared by combining a cementitious slurry with an uncured foamed resin and allowing the mixture to cure and harden. The resulting product is primarily cementitious material held in position with a hardened resin binder.
