Abstract: A cementitious composition, including for the molding of relatively light-weight, heat-insulative, nailable, structural units such as bricks, blocks, roof decking, etc. The composition may include an inorganic cementitious settable admixture within which is incorporated a significant proportion of waste industrial products, such as concrete, blacktop, windmill blades, brick chips, plastics, cordierite, tires, stack dust and/or fly ash, ceramics, clays, metals and plastics. The waste industrial products may be incorporated into the composition in various proportions.

Abstract: The present invention is directed to a retaining wall system including a retaining wall having with at least one retaining wall rebar extending along a vertical direction, the at least one retaining wall rebar includes an end formed into a first retaining wall rebar hook, at least one deadman spaced from the retaining wall, each deadman including a concrete base extending along the vertical direction, the concrete base including rebar extending past the concrete base and having an end formed into a deadman rebar hook, at least a first hole at a top portion of the retaining wall and extending into the retaining wall to expose the retaining wall rebar hook, and a first cable attached to the retaining wall rebar hook and to the deadman rebar hook to support the retaining wall.

Abstract: The invention is an improved cementitious mixture used to form structural components that are strong, lightweight, heat and fire resistant, and very economical to produce. The material includes a mixture of cement, water, ribbon-like virgin polyethylene strips and aggregate materials. The aggregate preferably includes recycled industrial waste products. Examples of these industrial wastes include shredded tires, wood by-products, waste coal combustion by-products, recycled waste gypsum products, recycled industrial foundry sand, and waste foam products such a Styrofoam. This new cementitious material is strong and lightweight. It has a lower thermal conductivity than conventional concrete and therefore improved insulative properties. The use of industrial recyclables not only enhances the performance characteristics of the components made from this material but aids in maintaining the environment by providing a practical use for industrial waste.
