摘要:
A polymer masonry unit is disclosed that can include a polymer added to a quarry byproduct to manufacture a quality brick unit. The present disclosure solves the technological problem of providing a structurally sound brick or concrete alternative without the need for kiln firing, using traditionally unusable waste material. By combining quarry byproduct and a polymer, a polymer masonry unit can be fabricated having compressive strength and architectural utility. In one exemplary embodiment, fiber elements can be added to the byproduct and polymer mixture to increase structural stability. The present disclosure improves the performance of the system itself by providing a basic block or brick unit using an environmentally responsible manufacturing process that reduces cost and waste. The manufacturing process includes a polymer/base material that can be poured into molds that cures over a predetermined period, without the need for kiln firing.

Methods and compositions for the installation of scientifically engineered and constructed unpaved runways are disclosed herein. The compositions are heterogeneous mixtures produced by blending aliphatic or cyclic organic compounds with binders that chemically react with gravel, aggregate, and soil particles to create permanent bonds, resulting in a strengthened and stabilized surface. When blended into the aggregate of a runway surface, the organic compounds act as a carrier fluid, distributing the binder system evenly so particles of all sizes are thoroughly and uniformly coated with the composition. Once the composition is distributed, an adhesion promoting compound reacts with constituents in the aggregate to increase the formation and strength of chemical bonds between particles.
摘要:
A flexible or rigid heat-insulation material consisting of a sheet of at least one layer of closed-cell gas bubbles 1/16 inch to 1 inch in size filled with a gas selected from helium, argon, neon, krypton, xenon, carbon dioxide, and chlorodifluoromethane, and mixtures thereof. At least one heat reflective layer of aluminum film is adhesively attached to the layer of gas bubbles or an aluminum film is vapor-deposited on the layer of gas bubbles.

A stone based copolymer substrate includes calcium carbonate (CaCO3) from approximately fifty to eighty-five percent (50-85%) by weight and varying in size generally from 1.0 to 3.0 microns, high-density polyethylene (HDPE) from approximately two to twenty-five percent (2-25%) by weight and a biopolymer from approximately two to twenty-five percent (2-25%) by weight. The substrate may include a biodegradation additive from approximately three fourths of a percent to two percent (0.75-2%) by weight. By selectively adjusting the ranges of the substrate's components, various products can be made to replace current tree-based and plastic-based products. The substrate can be configured to be tear proof, water proof, fade resistant and fire retardant while utilizing less energy and producing less waste during its manufacture. In an exemplary embodiment of the invention, the stone used in the substrate includes limestone.
摘要:
Products for obtaining masses for pouring, bricks, tiles and any other format are achieved, in which participate aggregates and asphaltic binders, as well as also additives for regulating the process. The invention achieves a remarkable increase in the capacity of neutrons, X-rays and/or photons radiation protection, and for this the use of asphaltic hydrocarbon as binder has been envisaged, while as aggregate is used Colemanite in absorption and attenuation of neutrons, Barite in the case of X-rays and Magnetite, Hematite and/or Steel shot in the case of photons.
摘要:
An acoustical plaster system features a base layer mixture and a finish layer mixture. The base layer mixture includes a first binder, a first thickener and a plurality of first particles, with the first particles being porous, lightweight, non-close packing particles having a first mean diameter. The finish layer mixture includes a powder latex binder, a second thickener and a plurality of second particles, with the second particles being porous, lightweight particles having a second diameter. The first mean diameter is larger than said second mean diameter.
摘要:
The invention is directed to a plastic fiber article of manufacture having composite-like high strength characteristics. The article of manufacture can be in the form of a panel or board. The panel or board is constructed from low cost fiber materials, industrial grade or high thermal plastic, and other additives to protect the board or panel from ultraviolet light, fugi growth, excessive heat, fire, insect infestation, and/or weathering. The plastic fiber panel or board may be textured and colored to resemble natural wood such as cedar, walnut, or oak. The plastic fiber panel or board is stronger more durable and may be cheaper than natural wood alternative panels or boards.
