Claims (1)

Patent- Anspruch:Patent claim: 3535 ringere Zeit und geht tiefer in die Formlinge hinein, und es entstehen schließlich Steine, welche ungefähr io Prozent leichter sind als solche, die bisher aus dichter Schlacke allein hergestellt wurden. Die Steine besitzen ferner eine gewisse, für das Haften des Mörtels wesentliche Porosität. Ihr leichteres Gewicht ermöglicht einen entsprechend weiteren Transport. Außerdem sind die Steine billiger, weil das Mahlen der Schlacke teuer ist und nicht die ganze Schlacke gemahlen zu werden braucht. Unter gemahlener Schlacke wird diejenige Schlacke verstanden, welche an der Luft erstarrt ist und später gemahlen oder zerfallen ist. Die Versuche haben gezeigt, daß man vorteilhaft ein Gemenge von etwa 50 Prozent gekörnter Schlacke mit etwa 50 Prozent an der Luft erkalteter Schlacke (Schlackenmehl) verwendet, und daß derartige Steine einen Druck von über 300 Atmosphären pro Quadratzentimeter aushalten. Für manche Fälle kann ein Kalkzusatz gegeben werden.less time and goes deeper into the bricks, and finally stones are created, which are about 10 per cent lighter than those which hitherto consisted of dense slag alone were manufactured. The stones also have a certain porosity, which is essential for the adhesion of the mortar. Your lighter weight enables further transport accordingly. Also, the stones are cheaper because grinding the slag is expensive and does not need to grind all of the slag. Ground slag is understood to mean that slag which solidifies in the air and later ground or disintegrated. The tests have shown that a mixture of about 50 percent is advantageous granular slag with about 50 percent of the slag cooled in the air (slag meal) used, and that such stones have a pressure of over 300 atmospheres per square centimeter endure. In some cases, an additive of lime can be given.
