Description

  

  Verfahren     zur    Herstellung einer beim Erstarren wasserdicht werdenden, Zement       enthaltenden    Nasse und deren     Überführung    in geformten Zustand.    Die vorliegende Erfindung betrifft     ein     Verfahren zur Herstellung einer beim Er  starren wasserdicht werdenden, Zement ent  haltenden Masse und deren Überführung in  geformten Zustand, welches dadurch gekenn  zeichnet ist, dass man Zement, Wasser,     Al-          kalicarbonat,    organische     Säure    und einen  Kohlenwasserstoff vermischt und die so er  haltene Masse formt. Das Verfahren kann  bei der Ausführung von Dichtungsarbeiten,  Trockenlegungen,     Unterwasserbauten.    usw.

    angewendet werden. Wie Versuche gezeigt  haben, können nach dem vorliegenden Ver  fahren Massen     erhalten    werden, die im Ge  gensatz zu solchen nach bekannten Ver  fahren hergestellten, nicht zu rasch körnig  werden, so dass sie leicht verarbeitet     werden     können. Ferner haben weitere Versuche er  geben, dass sich Massen nach dem vorlie  genden Verfahren erzielen lassen, die im ge  formten Zustand unter Wasser, auch vor  Beendigung des     Abbindens,    unter dem Ein  fluss des Wassers nicht leiden, zum Beispiel  ein Wegschwemmen von     ltlasseteilchen    durch  strömendes Wasser nicht erfolgt.

   Weiter    können nach dem vorliegenden Verfahren  Massen hergestellt werden, die durch Spritz  verfahren geformt werden können, was zum  Beispiel für eine Abdichtung von Tunnel  wandungen usw. von Bedeutung ist. Eine  Prüfung der Festigkeit nach dem Verfahren  hergestellter Erzeugnisse zeigte, dass die ver  wendeten speziellen Zusätze dieselbe nicht  ungünstig beeinflussen, sondern eher noch eine       Zunahme    der Festigkeit eintritt, gegenüber  Produkten, die ohne die bei dem vorliegenden  Verfahren verwendeten Chemikalien herge  stellt wurden.  



  Als     Alkalicarbonate    können Soda und  Pottasche verwendet werden. Als organische  Säure hat sich besonders Essigsäure bewährt.  Geeignete     Kohlenwasserstoffe    sind Petro  leum, Benzin usw. Zur Erzielung einer       mörtel-        bezw.        betonähnlichen    Masse kann  man dem Gemisch noch     Sand        bezw.    Kies zu  mischen.  



  Das Verfahren     gemäss    der     Erfindung     kann beispielsweise wie folgt ausgeführt wer  den:     Man    vermischt 110     gr    Wasser, 60     gr     Soda, 2     gr    Essigsäure und 6     gr        Petrol    in der      Wärme und fügt dem so erhaltenen Ge  misch 2 kg Zement und 1,3 kg Wasser zu.  Die so erhaltene Masse wird in Fugen ver  strichen, die gegen Austritt von Wasser ver  schlossen werden sollen.



  Process for the production of a cement-containing liquid which becomes watertight on setting and converting it into a shaped state. The present invention relates to a process for the production of a cement containing mass, which becomes rigid when it is rigid, and its conversion into the shaped state, which is characterized in that cement, water, alkali carbonate, organic acid and a hydrocarbon are mixed and the so he shapes keeping earth. The method can be used in the execution of sealing work, drainage, underwater structures. etc.

    be applied. As tests have shown, according to the present process, masses can be obtained which, in contrast to those produced by known processes, do not become granular too quickly, so that they can be easily processed. Furthermore, further tests have shown that masses can be achieved according to the present process that do not suffer under the influence of water in the formed state under water, even before the end of the setting, for example a wash away of oil particles by flowing water not happened.

   Furthermore, according to the present process, masses can be produced which can be molded by injection molding, which is important for sealing tunnel walls, etc., for example. A test of the strength of products manufactured according to the method showed that the special additives used did not have an unfavorable effect on the same, but rather an increase in strength occurs compared with products that were manufactured without the chemicals used in the present method.



  Soda and potash can be used as alkali carbonates. Acetic acid has proven particularly useful as an organic acid. Suitable hydrocarbons are petroleum, gasoline, etc. To achieve a mortar or. concrete-like mass you can add sand or sand to the mixture. Mix gravel.



  The method according to the invention can for example be carried out as follows: 110 grams of water, 60 grams of soda, 2 grams of acetic acid and 6 grams of petroleum are mixed in the heat and 2 kg of cement and 1.3 kg of water are added to the resulting mixture . The mass obtained in this way is spread in joints that are to be closed ver against leakage of water.
