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.
Claims12
The construction of a building block, one manufactured substantially from waste materials by molding or extruding into a high strength and multiple sided integrated block, said block having a formulation of ingredients including:
- class C fly ash in a range of about fifty percent (50%) to about ninety percent (90%) by weight of the molded block;
- ground celluostic material such as wood chunks, wood shavings, wood chips and textile byproducts, mixed in the formulation between about fifteen percent (10%) to fifty percent (50%) by weight of the mixed formulation;
- water;
- and,
- a plasticizer agent in the range of about 0.25 ounces to about 30 ounces by hundredweight of the fly ash in the mixed formulation.
