Description

  

  Procédé de fabrication d'un matériau à base de liège et de ciment  et matériau obtenu par ce procédé    Le liège étant le matériau naturel présentant les       caractéristiques        optimales    d'isolation phonique et  thermique, on conçoit l'intérêt qu'il peut y avoir à  l'utiliser dans la construction.  



  Comme, par ailleurs, ce matériau ne présente  pas une caractéristique de résistance mécanique per  mettant de l'utiliser seul en construction, il est donc  nécessaire de lui     adjoindre    un support     résistant    mé  caniquement.  



  C'est dans cet esprit qu'il a déjà été proposé  d'utiliser des agglomérés de liège et de ciment, ces  agglomérés proposés antérieurement n'ayant toute  fois pas permis d'obtenir des résultats pratiques uti  lisables.  



  La présente invention a pour objet un procédé  dont le but est de permettre de fabriquer un ma  tériau de     construction    à base de liège et de ciment  de bas prix de revient, présentant des très bonnes  caractéristiques d'isolations phonique et thermique  et une résistance mécanique, qui - sans être très  grande - est toutefois suffisante     pour    bien des       utilisations,    par exemple pour le     remplissage    de  murs ou de cloisons.  



  Le procédé selon l'invention est caractérisé en  ce qu'il comporte la suite des opérations     suivantes     a) Malaxage, pendant une durée de l'ordre de 5 à  10     mintues,    de  -     15    à     25        %        en        poids        de        granulé        de        liège,        et     -     environ    5 à     10        %        en        poids        d'eau,

          cette        eau     étant ajoutée en quantité telle que le granulé de  liège devienne juste saturé d'eau ;         b)        Adjonction        de        40    à     70        %        en        poids        de        ciment        et          d'une        quantité        supplémentaire        de        10    à     25     <RTI  

   ID="0001.0046">   %        en     poids d'eau, puis, second malaxage pour obtenir  l'homogénéité totale du mélange ;  c) Coulage du mélange dans des moules de formes  correspondant aux produits préfabriqués désirés ;  d) Démoulage et     stabilisation    du produit démoulé  pendant une durée de l'ordre de 30 heures;  e) Séchage à l'air libre sous abri pendant une  période de l'ordre de 20 jours.  



  A titre d'exemple particulier, des essais ont  montré que l'on obtenait des résultats     particulière-          ment    intéressants avec un matériau fabriqué selon  ce. procédé et dont la composition exacte est la sui  vante  - granulé de liège, d'une granulométrie de 2 à 4       mm    :     20        %        en        poids    ;  -     ciment        portland:        53        %        en        poids    ;

    -     eau        totale:        27        %        en        poids.     



  La présente invention a également pour objet le  matériau obtenu par le procédé défini ci-dessus.



  Process for the manufacture of a material based on cork and cement and material obtained by this process Cork being the natural material having the optimum sound and thermal insulation characteristics, it is easy to see the advantage that there may be in 'use in construction.



  As, moreover, this material does not have a characteristic of mechanical resistance allowing it to be used alone in construction, it is therefore necessary to add a mechanically resistant support to it.



  It is in this spirit that it has already been proposed to use agglomerates of cork and cement, these agglomerates proposed previously not having however made it possible to obtain useful practical results.



  The object of the present invention is a process the aim of which is to make it possible to manufacture a construction material based on cork and cement at a low cost, having very good sound and thermal insulation characteristics and mechanical resistance, which - without being very large - is however sufficient for many uses, for example for filling walls or partitions.



  The method according to the invention is characterized in that it comprises the sequence of the following operations a) mixing, for a period of the order of 5 to 10 minutes, from - 15 to 25% by weight of cork granule, and - approximately 5 to 10% by weight of water,

          this water being added in such an amount that the cork granule just becomes saturated with water; b) Addition of 40 to 70% by weight of cement and an additional amount of 10 to 25 <RTI

   ID = "0001.0046">% by weight of water, then, second mixing to obtain total homogeneity of the mixture; c) Pouring the mixture into molds of shapes corresponding to the desired prefabricated products; d) Demoulding and stabilization of the demolded product for a period of around 30 hours; e) Drying in the open air under cover for a period of around 20 days.



  As a specific example, tests have shown that particularly interesting results are obtained with a material manufactured according to this. process and the exact composition of which is the following - cork granule, with a particle size of 2 to 4 mm: 20% by weight; - Portland cement: 53% by weight;

    - total water: 27% by weight.



  A subject of the present invention is also the material obtained by the process defined above.
