Description

  

  Verfahren zur Herstellung eines faserhaltige Stoffe enthaltenden Betons.    Die Erfindung betrifft ein Verfahren    zur Herstellung eines faserhaltige Stoffe ent  haltenden Betons, welcher z. B. für die Her  stellung von leichten und isolierenden Plat  ten und andern Bauelementen verwendet  werden kann. Es ist bekannt, die zur Her  stellung solchen Betons verwendeten faser  haltigen Stoffe zu     mineralisieren,    das heisst  gegen äussere Einflüsse widerstandsfähiger zu  gestalten. Jedoch hat sieh gezeigt, dass je  nach den zur Behandlung des faserhaltigen  Materials verwendeten Zusatzstoffen ein der  art hergestellter Beton für beispielsweise in  ihm verlegte Wasserleitungen, für     metallische          Befestigungsmittel        etc.    oxydierend wirkt.

    Ausserdem ist die     Haftung    des     Bindemittels     an solchen     mineralisierten,    faserhaltigen  Stoffen unvollständig und die     Ilerstellungs-          verfahren    erfordern eine Wärme- und Druck  behandlung, was kostspielige Fabrikations  anlagen ergibt; ferner sind lange     Verfor-          mungsdauern    der mit solchem Beton herge  stellten     Bauelemente    erforderlich.

      Mit dem erfindungsgemässen Verfahren  werden diese Nachteile dadurch umgangen,  dass zur     Herstellung    des Betons die     faser-          haltigen    Stoffe mit     Aluminiumsulfatlösung     und     Kalkmilch    vorbehandelt und darauf mit  einem Bindemittel     vermischt    werden. Die Be  handlung .der faserhaltigen Stoffe mit     Alu-          miniumsulfatlösung    bewirkt, dass diese Stoffe  in ganz kurzer Zeit durchtränkt und aufge  weicht werden. Die     Kalkmilch        vervollständigt     die     Imprägnation    der faserhaltigen Stoffe.

    Diese werden infolge dieser Behandlung  widerstandsfähig gegen Fäulnis, gegen An  griff von Insekten und wirken     feuerhemmend.     



  Als     faserhaltige    Stoffe können pflanzliche  Stoffe, wie z. B.     Holzabfälle,    Hobelspäne,  Holzwolle,     !\dachfasern,    Stroh und     dergI.,    so  wie tierische     Fasern,    z. B. Tierhaare, oder       eine        Mischung        von    pflanzlichen,     faserhaltigen     Stoffen und tierischen Fasern     verwendet     werden.  



  Geeignete Bindemittel sind: Zement,     Gips,     hydraulischer Kalk, Weisskalk, oder eine      Mischung einzelner dieser Stoffe, z. B.  Zement und Kalk: das     Bindemittel    kann  wenigstens zum Teil auch aus Abfallkalk,  z. B. aus     Karbidschlamm    der Azetylengas  fabrikation bestehen.  



       Zweckmässigerweise    werden der     Beton-          mischung    Zuschläge beigegeben, und als  solche kommen Sand, Schlacke, Ziegelschrot,  Tuff, Bims,     Kunstbims    und     dergl.    in Be  tracht.  



  Zur Verminderung des     Volumengewichtes     wird dem Betongemisch zweckmässig eine ge  ringe Menge Wasserstoffperoxyd und     Man-          21    in Suspension zugefügt:.  



  Das Verfahren kann beispielsweise wie  folgt durchgeführt werden:  <B>2</B>0 Volumenteilen Hobelspänen     wird    1       Volumenteil        Aluminiumsulfatlösung    von 10 "       8e    beigefügt. Nach     gleichmässiger    Durch  tränkung wird 1 Volumenteil Kalkmilch zu  gefügt.     Dem    so vorbehandelten     faserhaltigen     Material werden 6 Volumenteile     Zement.     Sand und Wasser beigemengt und nach voll  ständiger     Durchmischung    kann der so herge  stellte Beton zu Formkörpern verarbeitet  werden.



  Process for the production of a concrete containing fibrous substances. The invention relates to a method for producing a fibrous materials ent containing concrete, which z. B. for the manufacture of lightweight and insulating Plat th and other components can be used. It is known to mineralize the fibrous materials used to manufacture such concrete, that is to say to make them more resistant to external influences. However, it has been shown that, depending on the additives used to treat the fiber-containing material, a concrete produced in this way has an oxidizing effect on, for example, water pipes laid in it, for metallic fasteners, etc.

    In addition, the adhesion of the binder to such mineralized, fiber-containing substances is incomplete and the Ilerstellungs- process require a heat and pressure treatment, which results in expensive manufacturing plants; Furthermore, long deformation times are required for the structural elements made with such concrete.

      With the method according to the invention, these disadvantages are avoided by pretreating the fiber-containing substances with aluminum sulfate solution and milk of lime and then mixing them with a binding agent to produce the concrete. The treatment of the fibrous materials with an aluminum sulphate solution causes these materials to be soaked and softened in a very short time. The milk of lime completes the impregnation of the fibrous substances.

    As a result of this treatment, these become resistant to decay and attack by insects and are fire-retardant.



  As fibrous substances, vegetable substances such as. B. wood waste, wood shavings, wood wool,! \ Roof fibers, straw and the like., As well as animal fibers, z. B. animal hair, or a mixture of vegetable, fibrous substances and animal fibers can be used.



  Suitable binders are: cement, gypsum, hydraulic lime, white lime, or a mixture of some of these substances, e.g. B. cement and lime: the binder can at least partly also consist of waste lime, e.g. B. made of carbide sludge of acetylene gas manufacture.



       Conveniently, aggregates are added to the concrete mixture, and sand, slag, crushed brick, tuff, pumice, synthetic pumice and the like come into consideration.



  To reduce the volume weight, a small amount of hydrogen peroxide and man-21 in suspension is expediently added to the concrete mix.



  The process can be carried out, for example, as follows: <B> 2 </B> 0 parts by volume of wood shavings 1 part by volume of aluminum sulfate solution of 10 "8e is added. After evenly soaking, 1 part by volume of milk of lime is added. The fibrous material thus pretreated becomes 6 parts by volume of cement Sand and water are added and, after thorough mixing, the concrete produced in this way can be processed into molded bodies.
