Abstract

Rubber residues (I) are useful in mixts. with hydratic and/or hydraulic binders (II) and additives, for producing constructional materials (III) for the building and mining industries. Also claimed are constructional materials (III) contg. 1-90 (pref. 50) wt.% (I) in the form of granules, dust or flour, milled or mixed with (II) etc. as above. Specifically water and additives are added to control the setting process, and the solids demand is less than 1.4 t/m3. USE/ADVANTAGE - (I) are useful esp. for the prodn. of lightweight building blocks (IIIA) (claimed). Also claimed are blocks (IIIA) as such, with bulk density below 1.6 t/3. The invention provides a new application for residues from rubber prodn. and processing, most of which would otherwise be dumped. Prods. (III) have low specific air consumption, low abrasive wear, good adhesion to buildings, low bulk density (wet) and low solids demand; they can be pumped over long distances with low pressure pumps (even with low water content and high viscosity), and their compsn. can be adjusted to give the required elastic deformation for use in deformable or crushable elements with defined working characteristics. Other applications include pumpable unset mortar or concrete, reinforced packing, and sealing material for back filling and void filling in mines, etc.

Description

In der Gummi herstellenden und/oder verarbeitenden Industrie fallen regelmäßig erhebliche Gummireste an. Das Restgummi kann nur zu einem geringen Anteil als Regenerat in qualitativ niedrigwertige Produkte eingebracht werden. Im übrigen muß das Restgummi depo­ niert und entsorgt werden. - Hier setzt die Erfindung ein.Fall in the rubber manufacturing and / or processing industry regularly considerable rubber residues. The remaining rubber can only a small proportion as regrind in low quality Products are introduced. Otherwise, the residual rubber must be deposited be kidneyed and disposed of. - This is where the invention begins.

Zur Lösung dieser Aufgabe lehrt die Erfindung die Verwendung von Restgummi in Mischung mit einem hydratischen und/oder hydrau­ lischen Bindemittel und Zuschlagstoffen zur Herstellung von Bau­ stoffen für die Bauindustrie und den Bergbau. - Bekanntlich werden bei Beton als Bindemittel Zement, bei Mörtel Zement, Kalk, Gips oder andere Bindemittel verwendet. Im Rahmen der Erfindung finden daher vorzugsweise Zement, Anhydrit und Calciumsulfat-Halbhydrat als Bindemittel Verwendung. Im übrigen unterscheiden sich Beton und Mörtel durch die Korngröße des Zuschlagstoffes aus Fein- und Grob­ sand bzw. aus Sand, Fein- und Grobkies.To achieve this object, the invention teaches the use of Residual rubber mixed with a hydrated and / or hydrau Binder and aggregates for the manufacture of construction fabrics for the construction and mining industries. - Become known cement for cement, cement, lime, gypsum or mortar other binders are used. Therefore, within the scope of the invention preferably cement, anhydrite and calcium sulfate hemihydrate as Binder use. Otherwise, concrete and Mortar due to the grain size of the aggregate of fine and coarse sand or from sand, fine and coarse gravel.
