Building block and system for manufacture

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.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] The subject matter of this continuation-in-part patent application is related to the subject matter of the continuation-in-part application having Ser. No. 10 / 815,533, which was filed on Apr. 1, 2004, which claims priority to the non-provisional patent application Ser. No. 10 / 411,551 which has a filing date of Apr. 10, 2003, which claims priority to the provisional patent application having Ser. No. 60 / 371,441, which was filed on Apr. 11, 2002, and is owned by a common assignee.BACKGROUND OF THE INVENTION [0002] This invention relates principally to a building block, one that is constructed, generally of waste material, such as fly ash, and can be either extruded or compressed under pressure into the fabrication of a building block for constructing buildings or the like. [0003] There are numerous building blocks that are available in the art for use for the construction primarily of commercial industrial type of buildings, and even some ...

AI Technical Summary

Benefits of technology

[0011] Essentially, the building block of this invention can be fabricated of the open cavity type, but preferably, is constructed into the configuration of a solid block, thereby providing it with greater strength and less susceptible to fracture, because of the solid integrated nature of its construction. Because of the type of waste materials from which the block is fabricated, including wood pulp, or the like, the block will accept and hold a nail, screw, or the like, so that supplemental sheeting, rather exteriorly or interiorly, can be applied and held directly to it, during fabrication of a building. Furthermore, because of the inherent nature of its ingredients, it can also be subject to cutting by a power saw, or the like. In addition, the block of this invention, because of its mixture, has enhanced thermal resistant characteristics, as can be understood. In addition, it can be treated, with other ingredients, such as a boride, to render it termite and mold resistant. It can function as a sound insulation; even can be used as a sound wall in or near high-noise areas, like at airports and industrial parks, and as dividing walls for adjacent condominiums and apartments, to provide that type of insulation.

[0035] Another object of this invention is to improve the hydration of the mixture which results in a faster and more thorough chemical reaction of the components of the present invention.
