Die bisher bekannt gewordenen künstlichen Pflastersteine haben wegen verschiedener Mängel noch keine allgemeine Verbreitung gefunden. Die meisten derartigen Erzeugnisse, wie Tonsteine (Klinker) haben nicht die erforderliche Härte, nutzen sich also zu schnell ab. Andere, wie die Schlacken der Kupferhütten, haben wohl die genügende Härte, werden aber beim Gebrauch zu glatt,The so far known artificial paving stones have because of different Defects not yet found widespread. Most of such products, such as clay stones (clinker) do not have the required hardness, so they use up quickly. Others, like the slag from the copper works, probably have enough Hardness, but become too smooth with use,
ίο endlich sind wieder andere, wie Feldspatsteine, bei großer Härte zu spröde. Jedenfalls treten alle bisherigen künstlichen Steine gegenüber den natürlichen Steinen in den Hintergrund.ίο finally there are others again, like Feldspatsteine, too brittle if very hard. In any case, all previous artificial stones occur over against the natural stones in the background.
Ein Material, welches sehr hart ist, aber trotzdem eine große Zähigkeit und Widerstandsfähigkeit gegen Stoß, und Schlag besitzt und außerdem wegen seiner porösen Struktur nicht glatt wird, ist der gesinterte oder geschmolzene Bauxit, welcher bereits im Baugewerbe, z. B. zur Herstellung von Röhren, Kunststeinplatten u. dgl., sowie auch zu Schleifzwecken, an Stelle des natürlichen Naxosschmirgels, verschiedene Verwendung gefunden hat.A material that is very hard, but still great toughness and resistance against impact, and also does not become smooth because of its porous structure, is the sintered one or molten bauxite, which is already used in construction, e.g. B. for the production of tubes, Artificial stone slabs and the like, as well as for grinding purposes, instead of the natural Naxos emery, has found various uses.
- Die außergewöhnliche Härte und Zähigkeit dieses Materials kommt nun in günstigster Weise zur Geltung bei der den Gegenstand der vorliegenden Erfindung bildenden Verwendung des Bauxits oder sonstiger unreiner natürlicher Tonerde als Kunstpflasterstein zu Straßenbelägen aller Art. Es kommt noch hinzu, daß dem Steine leicht eine beliebige löcherige oder auch körnige Struktur, wie sie etwa eine grobkörnige Schmirgelscheibe besitzt, gegeben werden kann, so daß er auch beim Verschleiß stets eine rauhe Oberfläche bietet, auf welcher der Fuß gut haftet.- The extraordinary hardness and toughness of this material now comes in the cheapest Way to apply in the subject of the present invention forming the use of bauxite or other impure natural clay as artificial paving stone for road surfaces of all kinds. It comes in addition, that the stone can easily have any holy or granular structure, as it has about a coarse-grained emery disk, can be given so that even when it is worn, it always offers a rough surface on which the foot works well adheres.
Die Herstellung geschieht in bekannter Weise. Der Bauxit, besonders der eisenoxydreiche, wird bei hoher Temperatur, nötigenfalls unter Zusatz von Flußmitteln, bis zur vollständigen Sinterung erhitzt, alsdann bis zur zweckentsprechenden Feinheit zerkleinert und unter Zusatz eines Bindemittels, wie Ton, Zement, Asphalt ti. dgl. in die gewünschte Form gebracht und gebrannt.The production takes place in a known manner. The bauxite, especially the one rich in iron oxide, is heated at high temperature, if necessary with the addition of flux, until complete sintering, then until crushed to the appropriate fineness and with the addition of a binding agent such as clay, Cement, asphalt ti. Like. brought into the desired shape and fired.
