It should be recognized herein that the treated water in the amount of ten percent (10%) to approximately thirty percent (30%0 is applied to the mixture in forming the various blocks, as identified in the Tables herein, will include an additional ingredient of a plasticizer, such as that described in this application as available under the brand name PLP, from W. R. Grace & Co., in order to act as a wetting agent that accelerates the full wetting of the mixture materials, whether they be the fibrous material or the aggregates, to achieve complete moisturization of the ingredients before they are molded into the block form. It is also at this time that one of the accelerators or retarders may be included, in order to facilitate the mixing process, when the ambient temperatures may be in the significantly cold, or heat ranges, wherever this process is utilized.

As can be seen fromFIG. 7, the system for extruding, molding, or, compressing the industrial building blocks of this invention is readily disclosed. As noted, the ingredients for the block are processed by the system, as disclosed. For example, pre-ground wood chips, as at40, are delivered via a variablespeed walking floor41, to aconveyor42, to ahammer mill43, to provide a secondary grinding of the chips. The ground and pulverized wood will be conveyed to a roto-paddle blower44, and delivered byconduit tubing45, for emitting into the upper end of a cyclonewood chip hopper46, as can be noted. Support structure, as at47, provides the bracing necessary for structurally holding the system in place. From the cyclone wood chip hopper, the ground wood, which may include wood chips, wood dust, paper pulp, ground up cardboard, or any other of the pulp ingredients, are delivered to a variable speed rotary-air lock, as at48. At this juncture, the proper amount of the wood ingredient is delivered to a vibratingclassifier59, where the dust and extra fines are removed and sent to the fine hopper,50 byaugar51, as noted. At this point, into the pre-mixer52, fly ash from anoutside silo source53 is delivered by way of avariable speed auger54, to the pre-mixer. The fly ash may be generated and deposited into the silo from any coal fired power plant.

In addition to the delivery of the wood chip component, and the fly ash from external sources, water, by way of the positive displacement water pump,53a, is also metered into the feed water line after the pump via the positive displacement additive pumps,57 in an amount to provide it with the proper degree of texture that renders the mixture more pliable, and capable of being either molded, extruded, or compressed, as can be understood. The amount of the ingredients added, including the water, can be determined from the formulations as previously set forth.

From the pre-mixture, a variable speed mixer further mixes up the ingredients, as at52, and delivers it to a variable speed extruder, molder, or hydraulic press, that moves the formulated material in continuous lengths, as can be seen by the block exiting from the extruder die, as at58. At this juncture, the blocks may be cut to the desired lengths, which may be anywhere from inches, up to four feet through sixteen feet in length, as noted. At this point the cut blocks will then be conveyed upon theconveyor56, to a location for drying, curing, storage, or even for use for installation at a building site.

As an example of usage of the molding, compression, extruding process, utilizing the system. As can be seen fromFIG. 2, the batch system for extruding the industrial building blocks of this invention is readily disclosed. As noted, the ingredients for the block are processed by the system, as disclosed. For example, pre-ground wood chips, as at10, are delivered byconveyor11, to ahammer mill12, to provide a secondary grinding or pulverizing of the chips. The ground and pulverized wood will be conveyed by ablower13, to a roto-paddle blower14, and delivered byconduit tubing15, for emitting into the upper end of a cyclonewood chip hopper16, as can be noted. Support structure, as at17, provides the bracing necessary for structurally holding the system in place. From the cyclone wood chip hopper, the ground pulp, which may include wood chips, wood dust, paper pulp, ground up cardboard, or any other of the pulp ingredients, are delivered to a variable speed roto-feeder, as at18. At this juncture, the proper amount of the wood ingredient is delivered to a pre-mixer19, as noted. At this point, and into the pre-mixer, fly ash from anoutside silo source20 is delivered by way of apositive displacement compressor21, through aconduit22, to the pre-mixer. The fly ash may be generated and deposited into the silo from any of the variety of sources for this type of ingredient. For example, it may be the fly ash from a cement plant. Or, it may be the fly ash generated from many of the other installations that generate class C fly ash

In addition to the delivery of the wood chip component, and the fly ash from external sources, water, by way of theconduit23, is also metered into the pre-mixer, in an amount to provide it with some degree of texture that renders the mixture more pliable, and capable of being either extruded, or compressed, as can be understood. The amount of the ingredients added, including the water, can be determined from the formulations as previously set forth.

From the pre-mixture, a variable speed mixer further mixes up the ingredients, as at24, and delivers it to a variable speed extruder, that extrudes the formulated material in continuous lengths, as can be seen by the block exiting from the extruder dye, as at25. At this juncture, the blocks may be cut to the desired lengths, which may be anywhere from inches, up to four feet through sixteen feet in length, as noted. At this point the cut blocks will then be conveyed upon theconveyor26, to a location of drying, curing, storage, or even for use for installation at a building site.

The percentages of the ingredients for the block formulation when the sugar beet waste lime is applied may be determined from the following table.

In the formation of the blocks from the hydraulic or other pressure compressed blocks, the material will be formed similar in the manner as the pre-mix for the extruding, or molding process, including up to the delivery of the Class C fly ash and wood, etc, to the plant, for mixing, as previously explained. The material from the mixer, in the extruding process ofFIG. 2, will be left dry, and bagged, for delivery to the feed hopper, of the Encore Building Solutions, Inc., St. Louis, Mo. Another extruding process for compressing blocks, at low pressure, into the building block form may be obtained from Encore Building Solutions, Inc., of St. Louis, Mo.

Generally, the same formula is used as in the extruding process, but in the high pressure press, other blends will also work because of the pressure involved, up to three thousand pounds (200-600 lbs.) per square inch, which is further effective in forming the desire block.

The pre-mix is added to a feed hopper, with a blender, built into it. A liquid pump delivers water by way of a twelve volt marine type pump. This makes the press totally self contained, portable, and with the hydraulic press being provided directly upon the trailer frame, when constructed. Once the hydraulic engine is turned on, the pre-mix is poured into the feed hopper, delivered to the blender; some moisture is added, generally in the range of enough water to make a substantially viscous pre-mix. The press is then applied, after a batch of the materials provided into the mold, at the compression chamber, for immediately forming a block. A spray system may be used for adding the treated water at the blender/mixer, and the water tank assembly holds approximately one hundred gallons of water. The compression chamber, at the mold, may include a weighing device, to ensure that the proper amount of materials is added into the mold, before compression is initiated. The mold may also be constructed in a manner to provide the shape the block is desired, as for example, the mold may contain the semi circular protrusions, in order to form the

grooves

2 and3, within the finished block, when compressed. Also, the tongue and groove arrangements,5-8, can also be formed in a similar manner.

Blocks formed in the manner as described exhibit very little shrinkage once formed and used in wall formation. Furthermore, when subjected to a freeze-thaw test, ASTM C-679 ASTM C-1262, very little breakage or shattering of the blocks have been experienced. It has been found that the blocks, when formed into a wall, provide enhanced retarding against sound transmission through the wall when employed. Thus, there is a noise reduction. Apparently the blocks have a tendency to absorb sound.

Variations or modifications to the subject matter of this invention may occur to those skilled in the art upon reviewing the disclosure as provided herein. Such variations, if within the spirit of this development, are intended to be encompassed within the scope of the invention as described herein. The description of the preferred embodiment, and as shown in the drawings and schematics, is set forth for illustrative purposes only.
