Description
Verfahren zur Beschleunigung der Erhärtung von Zement Der Gegenstand der Erfindung ist, Zement so schnell erhärtend zu machen, daß mit ihm -Wasserdurchbrüche- in Kellern, Tunnels- usw: sofort verstopft werden können. Es ist bekannt, Zement mit Alkalilaugen, Wasserglas oder Lösungen von Chloriden von Kalk, Tonerde und Eisen zu mischen und durch diese Beimischungen eine schnellere Erhärtung des Zements zu erzielen.Method of accelerating the hardening of cement The object the invention is to make cement harden so quickly that with it -water breakthroughs- in cellars, tunnels, etc .: can be clogged immediately. It is known cement with alkaline solutions, water glass or solutions of chlorides of lime, clay and iron to mix and through these admixtures a faster hardening of the cement achieve.
Diese Verfahren haben den Übelstand, daß der mit diesen Flüssigkeiten - gemischte Zement nach kurzer Zeit spröde wird. Außerdem besteht in dem Hantieren mit konzentrierten Laugen und sauren Chloridlösungen die Gefahr, Hände und Gesicht zu verletzen. Da schnell erhärtender Zement auch zum Vergießen von Maschinenteilen verwendet wird, so kann durch Zusatz von Chloriden starkes Rosten von Eisenteilen hervorgerufen werden.-Diese Mängel werden durch die neue Erfindung beseitigt. Es wird nach dieser nicht wie bei den bekannten Verfahren eine Lösung, sondern ein Pulver verwendet, das, mit Zement und Wasser gemischt, eine plastische Masse bildet.These procedures have the disadvantage that of using these fluids - mixed cement becomes brittle after a short time. In addition, there is fiddling with concentrated alkalis and acid chloride solutions the risk to hands and face to hurt. As the fast-setting cement is also used for casting machine parts is used, the addition of chlorides can cause severe rusting of iron parts These deficiencies are eliminated by the new invention. It becomes after this not a solution, as in the known processes, but a Powder used, which, mixed with cement and water, forms a plastic mass.
Der Grundstoff dieses Pulvers sind die bei der Fabrikation von Aluminiumsulfat verbleibenden, kurz mit Si-Stoff bezeichneten Rückstände. Sie werden bekanntlich an Stelle von Traß als Zusatz zum Beton verwendet, " um diesem ein dichteres Gefüge zu geben und ihn so gegen die Einflüsse von aggressiven Wässern zu schützen. Für die neue Erfindung werden andere Eigenschaften des Si-Stoffs benutzt. - -Zu dem gedachten Zweck wird ein Gemisch von Si-Stoff, Calciumoxyd und calcinierter Soda verwendet, das mit Zement und Wasser eine plastische Masse bildet, die sich dadurch auszeichnet, daß sie sich beim Eindrücken in die Durchbruchstellen den Wandungen der öffnungen gut anschließt, in wenigen Minuten fest und nicht brüchig wird.The raw material of this powder are those used in the manufacture of aluminum sulphate remaining residues, briefly referred to as Si-substance. You will be known used instead of trass as an additive to concrete "to give it a denser structure to give and to protect it against the influences of aggressive waters. For the new invention uses different properties of the Si material. - -In addition The intended purpose is a mixture of silicon, calcium oxide and calcined soda used, which forms a plastic mass with cement and water, which is thereby is characterized by the fact that when it is pressed into the breakthrough points, the walls the openings are well connected, solid and not brittle in a few minutes.
Für die Wirkung des Pulvers ist es wichtig, daß in ihm Soda und. Calciumoxyd in einem bestimmten Verhältnis zueinander stehen. Es darf .nämlich nur so viel Calciumoxyd vorhanden sein, daß dieses nach Wasserzusatz ganz in das indifferente Carbonat, die Soda aber nur teilweise in Natronhydrat übergeführt wird. Durch letzteres werden aus dem Si-Stoff Tonerde und erhebliche Mengen Kieselsäure gelöst. Diese Lösung wirkt nicht nur auf den Si-Stoff, sondern auch auf den Zement erhärtend ein; dieser Vorgang wird aber wesentlich unterstützt durch die bei der Umsetzung des Calciumoxyds entstehende Erwärmung und die chemische Bindung von Wasser.For the powder to work, it is important that it contains soda and. Calcium oxide are in a certain relationship to each other. Namely, only that much calcium oxide is allowed be present that this after the addition of water is completely converted into the indifferent carbonate, the soda is only partially converted into sodium hydroxide. Be through the latter from the Si-substance alumina and considerable amounts of silica dissolved. This solution has a hardening effect not only on the Si material, but also on the cement; this The process is, however, significantly supported by the conversion of the calcium oxide resulting warming and the chemical bonding of water.
Es wird hier also nicht nur die Summe der Einzelwirkungen der an sich bekannten Stoffe erzielt, sondern es ist die Einwirkung der Stoffe aufeinander für die Erreichung der beabsichtigten einheitlichen Wirkung maßgebend.So here it is not just the sum of the individual effects of the per se known substances, but it is the action of substances on each other for the achievement of the intended uniform effect is decisive.
