Abstract: A compressed building block formed of a pre-mix of fly ash, either of the Class C type, is combined with either ground or pulverized wood chips, or with fine sand, and a plasticizer, and accelerator, then moisturized, and lastly either extruded or compressed in a mold into the configuration of a block. The block lacks a binder, except Portland cement for select military applications. A mold retardant may be added to the mixture, to provide the formed block with further beneficial attributes. The blocks may be formed by a system for extruding such blocks from the formulation, or they may be formed by means of a hydraulic or other press and pressed into the configuration of the desired block, needed for the construction.

Abstract: The production of packaging material for expanded polystyrene (EPS) includes randomly placing a piece of EPS of any size or shape across a first grid of wires, cutting the EPS into strips by heating the wires, allowing the strips to fall to a second grid of wires, and cutting the EPS strips by heating the second set of wires.
