Verfahren zur Herstellung von Gipsmörtel.

verwandt, deren Verarbeitung immer mit gewissen Sehwierigkeiten verbunden ist. Die bekannten Mörtelzusammensetzungen haben nämlich den Nachteil, dass sie nach dem Anrühren mit Wasser sehr schnell erstarren und deshalb sehr bald verarbeitet werden miissen.
Es wurde nun gefunden, dass dieser Nachteil durch Zugabe geringer Mengen anhydriseher Alkaliphosphate, z. B. von Natriumhexametaphosphat, vermieden und die Erstarrung des Mörtels dadurch verzögert werden kann.

Method of making gypsum mortar.
EMI1.1
related, the processing of which is always associated with certain difficulties. The known mortar compositions have the disadvantage that they solidify very quickly after being mixed with water and therefore have to be processed very quickly.
It has now been found that this disadvantage is remedied by adding small amounts of anhydric alkali metal phosphates, e.g. B. sodium hexametaphosphate, avoided and the solidification of the mortar can be delayed.
