Benefits of technology

[0010] It is therefore an object of the present invention to provide lightweight concrete composite blocks comprised of polystyrene, cement, water, and glass.
[0011] It is another object of the present invention to provide lightweight concrete composite blocks that do not introduce harmful chemicals into the environment.
[0012] It is a further object of the present invention to provide a method of manufacturing lightweight concrete composite blocks comprised of polystyrene, cement, water, and glass.
[0013] It is still a further object of the present invention to provide lightweight concrete composite blocks suitable for the building of retaining structures.

Problems solved by technology

While landscape timbers have functioned adequately, there are certain disadvantages in their use.
Unfortunately, the chemicals employed to treat the landscape timbers, in particular arsenic and creosote, are toxic and thus harmful to the environment.
Consequently, pollution occurs not only at production facilities but also at points of use since landscape timbers leach the treatment chemicals into the surrounding environment.
Furthermore, landscape timbers ultimately rot and decay necessitating replacement in addition to more fully delivering the treatment chemicals into the environment.

Embodiment Construction

[0017] As illustrated in FIGS. 1 and 2, a unitary lightweight concrete composite block 10 is rectangular with a horizontal axis greater than a vertical axis to facilitate stacking thereof for the building of retaining structures in the form of walls, enclosed areas, raised gardens, flower beds, and the like. While the preferred embodiment of the block 10 is rectangular to facilitate easier stacking thereof, those of ordinary skill in the art will recognize many alternative shapes, including but not limited to square, circular, triangular, polygonal, L-shaped, and the like.

[0018] The lightweight concrete composite utilized to form the blocks 10 includes polystyrene, which is typically recycled; cement, which is typically Portland; water; and glass, which is typically recycled, ground glass. The cement is stored in a hopper prior to delivery from the hopper into a mixer using suitable and well-known means such as an auger, conveyor belt, pneumatic blower, and the like. Likewise, the ...

Abstract

A lightweight concrete composite is utilized to form blocks. The lightweight concrete composite includes polystyrene, cement, water, and glass. The blocks are advantageous for building retaining structures in the form of walls, enclosed areas, raised gardens, flower beds, and the like because the blocks are lightweight, easily cut and stacked, and more importantly do not introduce harmful chemicals into the environment.
