Description

  

  Procédé de fabrication de béton armé dont l'agglomérant est du soufre.    La présente     invention    a     pour    objet un       pro,cé@dé    de     fabrication    ,d'un béton     armé,    dont  l'agglomérant ,est du soufre.  



  Il est connu que     1'n    peut obtenir un bé  ton en     incorporant    à     @du    soufre fondu     @de    la  pierre en poudre, -du sable     et,du    gravier, puis  en     laissant    refroidir .le mélange.

   On ,a fabri  qué ainsi des joints, des revêtements destinés  à rendre     résistantes    aux agents     chimiques     des parois de cuves,     etc.    Par contre, .on n'a  jamais fait avec le mélange de     produits    cités  plus haut, du béton armé,     probablement    parce       que        l'on     une attaque du fer, avec       formation    .de sulfure .de fer, ou même de sul  fate, au cas où une oxydation se produirait.  



  Les inventeurs ont trouvé que,     contraire-          ment    à ce     qué    l'on pouvait supposer, ces bé  tons à base de soufre peuvent     -également    être  armés comme le     béton    -de ciment;     les    fers ad  hèrent très bien ,au béton et ne subissent au  cune attaque, même après deux ans d'expé  rience.

      Selon la présente invention, on     incorpore     donc des     barres,d.e    fer à un mélange de soufre    fondu,     @de        poudtre        @de    pierres,     @de        sable    et de  gravier.  



       Ceci    peut être exécuté     comme    suit:  On     couledans    des coffrages, à l'intérieur       desquels    .on a     disposé    des fers. comme on le  fait pour la     construction        d'ouvrages    en     béton     de     .ciment,    un     mélange,de   <B>130</B>     parties    .de sou  fre fondu avec 270 parties de poudre de pier  res très fines, 270 parties -de     sable    et 330 par  ties,de gravier concassé.  



  Ce     mélange    est     préalablement        brassé    de  manière .à avoir une     composition    identique  dans toutes ses parties; il se refroidit rapide  ment après avoir été     coulé    et on peut,démou  ler     -dès    que le     béton,est    ,devenu solide par     re-          froidissement.     



  Le rôle de l'armature     est'très    important;       celle-ci    non seulement augmente la solidité<B>du</B>  béton -au soufre, mais lui permet de mieux  résister aux     variations    de température. Par  exemple, lorsque l'on     construit    des cuves en  béton de soufre, et que l'on chauffe -le li  quide qu'elles     contiennent,    il se produit fré  quemment des fentes dans la cuve, surtout  lorsque le     liquide    est     chauffé        au-dessus    de      GO   C.

   Le fait d'armer le béton -de soufre,  lors de la construction de la .cuve, rend     celle-          ci    non seulement beaucoup plus solide, mais  surtout beaucoup plus résistante aux varia  tions de     température,    même pour les cuves  construites d'une seule pièce.  



  Si l'on prend la précaution de construire  les cuves non plus en une pièce, mais en as  semblant entre elles des     segments    de béton de  soufre armé, que l'on fixe les uns     contre    les  autres en intercalant un joint élastique et sou  ple, on arrive à éviter complètement la for  mation de     fentes,    même loirs de fortes et brus  ques variations de température. Ceci ne pou  vait pas être prévu, car :on pouvait craindre       une    dilatation     différente,    du béton de soufre  et du fer, ce qui aurait entraîné nécessaire  ment la formation de fentes; or,     l'expérience     montre que c'est le contraire qui se produit.

           L'armature    se fait     exactement    d'après la  même     technique    que pour le béton de ciment.  On petit     également    employer des barres rouil  lées pour faciliter     l'adhérence    du béton.



  A process for manufacturing reinforced concrete in which the binder is sulfur. The present invention relates to a pro, cé @ de production of a reinforced concrete, the binder of which is sulfur.



  It is known that concrete can be obtained by incorporating powdered stone, sand and gravel into molten sulfur, and then allowing the mixture to cool.

   Seals, coatings intended to make tank walls resistant to chemical agents, etc. have thus been manufactured. On the other hand, we have never done with the mixture of products mentioned above, reinforced concrete, probably because we attack the iron, with the formation of iron sulphide, or even sul fate, in case where oxidation occurs.



  The inventors have found that, contrary to what one might suppose, these sulfur-based concrete can also be reinforced like cement concrete; the irons adhere very well to concrete and do not undergo any attack, even after two years of experience.

      According to the present invention, bars are therefore incorporated, d.e iron in a mixture of molten sulfur, @ powder @ stones, @ sand and gravel.



       This can be done as follows: It is poured in formwork, inside which .on has placed irons. as is done for the construction of cement concrete structures, a mixture of <B> 130 </B> parts of molten sulfur with 270 parts of very fine stone powder, 270 parts of sand and 330 parts, crushed gravel.



  This mixture is previously stirred so as to have an identical composition in all its parts; it cools rapidly after being poured and can be demolded as soon as the concrete has become solid by cooling.



  The role of the frame is very important; this not only increases the strength of the <B> concrete </B> to sulfur, but allows it to better resist temperature variations. For example, when constructing sulfur concrete tanks, and heating the liquid they contain, cracks frequently occur in the tank, especially when the liquid is heated above. by GO C.

   The fact of reinforcing the concrete with sulfur, during the construction of the tank, makes it not only much more solid, but above all much more resistant to temperature variations, even for tanks constructed from a single room.



  If we take the precaution of building the tanks no longer in one piece, but by appearing between them segments of reinforced sulfur concrete, which we fix against each other by inserting an elastic and flexible joint, the formation of cracks can be completely avoided, even during strong and sudden variations in temperature. This could not be foreseen, because: one could fear a different expansion, sulfur concrete and iron, which would have necessarily led to the formation of cracks; however, experience shows that the opposite is true.

           The reinforcement is done according to exactly the same technique as for cement concrete. Rusted bars can also be used to facilitate the adhesion of the concrete.
