Description

Feuerfester Mörtel Gegenstand des Hauptpatents 549 262 ist ein Mörtel für Silikamauerwerk, der aus einem hochkieselsäurehaltigen Grundstoff und einem Kalkzusatz besteht, der sich vorteilhafterweise zwischen 2 und 4 °(o bewegt.Refractory mortar The subject of the main patent 549 262 is a mortar for silica masonry made from a high silica base material and a There is an additive of lime, which is advantageously between 2 and 4 ° (o.

Es ist bereits bekannt, bei der Herstellung von Silikasteinen dem kieselsäurehaltigen Grundstoff den Kalkzusatz in Form von Calciumphosphat beizugeben. Gemäß der Erfindung soll der Kalkzusatz des Mörtels teilweise, etwa zur Hälfte, aus gelöschtem Kalk, zur anderen Hälfte aus Calciumphosphat bestehen. Der Zusatz des gelöschten Kalkes erhöht bekanntlich das Bindevermögen des Mörtels, während der Zusatz des Phosphates die Bildung von Tridymit fördert. Durch Zugabe beider Arten des Kalkes wird also sowohl die Bindefähigkeit als auch die Feuerfestigkeit des Mörtels erhöht; es zeigte sich ferner, daß ein derartiger Mörtel mit einer besonders geringen Menge von Wasser, gegebenenfalls auch ohne den Zusatz von Sulfitablauge zu einer pastenartigen, gut verarbeitungsfähigen Masse angerührt werden konnte.It is already known in the manufacture of silica stones add the lime additive in the form of calcium phosphate to the base material containing silica. According to the invention, the addition of lime in the mortar should be partially, approximately half, made of slaked lime, the other half of calcium phosphate. The addition of the slaked lime is known to increase the binding capacity of the mortar, while the addition of phosphate promotes the formation of tridymite. By adding both Types of lime will be both the binding capacity and the fire resistance of mortar increased; It was also found that such a mortar with a special small amount of water, possibly without the addition of sulphite waste liquor could be mixed to a paste-like, easily processable mass.
