Abstract:
The present invention relates to a composite material, particularly a composite material for ceramic tiles, stone cladding, surface tops (e.g. worktops), and the like. The composite materials are typically derived from waste products. The composite materials of the present invention are formed from a glass component and a non-glass mineral component (e.g. ceramics and/or glaze). Generally the composite materials do not require any binders (especially synthetic binders) to hold the materials together. Therefore, the composite materials and products made therefrom are typically recyclable.
Abstract:
Vorgestellt wird eine Verstärkung für einen Werkstoff aus einer formbaren Masse, insbesondere für einen Baustoff, wobei in der Verstärkung als Komponenten Gerstengrannen (4) und Flugschirmchen (1) von Samen, insbesondere von Rohrkolbensamen, vorhanden sind. Dabei weisen die Flugschirmchen Stammfasern (2) und davon abzweigende Seitenfasern (3) auf, wobei die Seitenfasern (3) der Flugschirmchen (1) durch die Gerstengrannen (4) miteinander verbunden sind. Der Gewichtsanteil der Gerstengrannen (4) ist etwa 0,1 bis etwa 2 mal, beispielsweise etwa 0,5 bis etwa 1 mal, so hoch ist wie der Gewichtsanteil der Flugschirmchen (1). Die Erfindung betrifft ferner einen Baustoff mit der geschilderten Verstärkung und ein Verfahren zum Herstellen des Baustoffs.
Abstract:
The present invention relates to a concrete composition which is economical and environmentally friendly by: utilizing oxidizing slag which is a by-product generated during an electric arc furnace steelmaking process as a fine aggregate; enhancing the entire strength of the concrete; and drastically reducing the cement content within the concrete, and relates specifically to a high performance concrete composition using slag which comprises 8-16 weight% of rapid-hardening cement, 3-6 weight% of water, 28-59 weight% of fine aggregate, and 30-50 weight% of coarse aggregate, wherein 30-100% of the fine aggregate is slag. Strength can be enhanced and manufacturing costs can be saved by reducing the content of cement constituting the above-mentioned concrete composition and replacing most of the fine aggregate with electric arc furnace oxidizing slag.

Abstract:
A composite building material includes carpet waste having carpet fibers and adhesive, and an inorganic filler that includes fly ash. The composite building material may be produced by providing the carpet waste, mixing the carpet waste with the inorganic filler to produce a homogeneous blend, and forming the homogeneous blend into the composite building material. The composite building material may optionally include a base polymer, slack wax, and/or calcium carbonate.
Abstract:
A method for decorating an artificial stone laminate, for example, a quartz resin composite is provided. In the manufacturing process, a substantially thin layer of transparent or translucent particulates is deposited on a release surface. Color pigments or any coloring material that imparts color and/or contrast are selectively deposited in areas on the transparent or translucent particulates to create patterns and designs. A layer of reinforcing fibers, for example, glass fibers, is placed on the layer of transparent or translucent particulates. A binder, deposited on the layer of reinforcing fibers, fills gaps between the transparent or translucent particulates and binds the reinforcing fibers to the transparent or translucent particulates. After the artificial stone laminate cures, the artificial stone laminate is polished to expose a flat, transparent or translucent surface of the transparent or translucent particulates that have been selectively colored by the coloring material to create visual patterns and designs.
Abstract:
A composition comprising purposely oriented lignocellulosic fiber bound to an inorganic hydrate such as gypsum in the absence of water using a polymer. In a preferred embodiment the polymer is polyurethane. A process for producing the composition and a wide variety of applications of the composition are also described.
Abstract:
A method of applying building a pavement structure using a polymer modified hot- applied tack coat is disclosed. This polymer modified tack coat is non-adhesive at ambient temperatures, and, thus, also non tracking. The tack is applied while hot, but cools quickly. The subsequent application of hot mix asphalt results in a superior bond between the asphalt layer and the tack layer. It is particularly well suited to bonded friction course applications since it removes the necessity of specialized spray paving machinery and allows the use of conventional asphalt distributors and pavers.
Abstract:
Gegenstand der Erfindung ist eine bitumenfreie Baustoffzusammensetzung, welche eine Polymerdispersion oder ein entsprechendes Redispersionspulver, insbesondere auf Basis vorzugsweise wässrig redispergierbarer Emulsionspolymere, zusammen mit Polystyrolpartikeln, Teilchen aus vulkanisiertem Naturkautschuk, vulkanisiertem synthetischen Kautschuk, thermoplastischem Kautschuk oder Mischungen davon und auf Basis von organischen Polymeren ausgebildete synthetische Mikrohohlkugeln, sowie gegebenenfalls mindestens einem anorganischen Bindemittel und gegebenenfalls weiteren Additiven enthält, wobei die Baustoffzusammensetzung frei ist von keramischen Mikrohohlkugeln. Die erfindungsgemäße Baustoffzusammensetzung kann grundsätzlich als 1 K-, 2K- oder auch Mehrkomponenten-Anwendungssystem formuliert werden. Die erfindungsgemäße bitumenfreie Baustoffzusammensetzung zeigt neben ausgezeichneten Abdichtungseigenschaften, wie sie üblicherweise nur mit bitumenhaltigen Abdichtungsmassen erreicht werden können, insbesondere ein ausgezeichnetes Schrumpfverhalten nach dem Auftrag.
Abstract:
The invention relates to a method for manufacturing an insulating composite containing mineral fibers, aerogel and binder. This method implies the step of suspending the fiber webs and aerosol in an air flow thereby disentangling the fiber webs and mixing fibers, aerosol and eventually binder homogeneously. The apparatus described combines spinning of the fibers, collecting them as webs, disentangling the fiber webs in suspended air, mixing the fibers with aerogel and cement as well as pressing and curing the mixture to a consolidated product of densitiy 150 to 800 kg/m3.
