Description

Verfahren zum Verhindern des Erhärtens wässeriger Baustoffmischungen Bei der Herstellung von gebrauchsfertigem Zementmörtel oder Kalk- oder Zementmilch ist es möglich, zum Verhindern des Erhärtens diese wässerigen Baustoffmischungen einfrieren zulassen.Process for preventing the hardening of aqueous building material mixtures In the production of ready-to-use cement mortar or lime or cement milk it is possible to prevent the hardening of these aqueous building material mixtures Allow freezing.

Die Weiterbehandlung und Verwendung der gefrorenen Baustoffmischungen kann erschwerlich sein, z. B. beim Wiegen, Zuteilen und Befördern.The further treatment and use of the frozen building material mixes can be cumbersome, e.g. B. weighing, allocating and transporting.

Es ist zweckmäßig, diese Nachteile auszuschließen. Es wurde gefunden, daß dies dadurch möglich ist, wenn die wässerigen Baustoffmischungen nach Zusatz eines Kälteschutzmittels, wie beispielsweise Glycerin od. dgl., auf so tiefe Temperaturen abgekühlt werden, die das Erhärten verhindern, ohne jedoch die Baustoffmischung zum Gefrieren zu bringen.It is useful to eliminate these disadvantages. It was found, that this is possible when the aqueous building material mixtures after addition a cold protection agent, such as glycerine or the like, to such low temperatures which prevent the hardening, but without the building material mixture to freeze.

PATENTANSPRUCH: verfahren zum Verhindern des Erhärtens von Zementmörtel, Kalkmilch oder Zementmilch, dadurch gekennzeichnet, daß die wässerige Baustoffmischung nach Zusatz .eines Kälteschutzmittels auf so tiefe Temperaturen abgekühlt wird, die das Erhärten verhindern, ohne jedoch die Baustoffmischung zum Gefrieren zu bringen. PATENT CLAIM: a method to prevent cement mortar, milk of lime or cement milk from hardening, characterized in that the aqueous building material mixture is cooled to such low temperatures after the addition of an anti-freeze agent that prevents hardening without, however, causing the building material mixture to freeze.
