KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung . betrifft ein Verfahren zur Herstellung von Kunststeinen und beruht darauf, Zechstein unter Zusatz von Zement und Magnesia unter Druck zu formen und dann an der Luft erhärten zu lassen.Present invention. relates to a process for the production of artificial stones and is based on forming Zechstein under pressure with the addition of cement and magnesia and then let harden in the air.
Die nach diesem Verfahren erhältlichen Produkte besitzen gegenüber den bekannten Kunststeinen, insbesondere gegenüber jenen aus Zement und Sand, wichtige und überraschende Vorteile.The products obtainable by this process have compared to the known Artificial stones, especially those made of cement and sand, are important and surprising Advantages.
So ist das nach vorliegendem Verfahren erhältliche Produkt, sowie es aus der Form kommt, gut hantierbar und erhärtet schon innerhalb weniger Tage derart, daß man es auf einen gepflasterten Boden fallen lassen kann, ohne daß es zerspringt. Die bekannten Kunststeine aus Sand und Zement dagegen sind nach dieser Zeit kaum hantierbar und erfordern zum Erhärten Wochen. Ein weitererSo is the product obtainable by the present process, as well as it from the mold comes, easy to handle and hardens within a few days so that you can can drop onto a paved floor without cracking. The known Artificial stones made of sand and cement, on the other hand, are hardly manageable after this time and require weeks to harden. Another
2o~\^orteil der vorliegenden Masse besteht darin, daß nur eine verhältnismäßig geringe Menge von Bindemitteln erforderlich ist. Es genügt, zu 4 Teilen des angewendeten Zechsteins nur ι Teil Zement zuzusetzen, während, wenn Zement mit Sand geformt wird, höchstens 3 Teile Sand mit 1 Teil Zement gemischt werden dürfen.The advantage of the present mass is that that only a relatively small amount of binders is required. It is sufficient, add only ι part of cement to 4 parts of the Zechstein used, while if Cement is molded with sand, no more than 3 parts of sand mixed with 1 part of cement may be.
Von den bekannten Kunstsandsteinen ist vorliegende Masse dadurch unterschieden, daß zum Erhärten kein hoher Dampfdruck erforderlich ist.The present mass is distinguished from the known artificial sandstones in that no high steam pressure is required for hardening.
Das Verfahren wird zweckmäßig in der Weise ausgeführt, daß man 4 Teile Zechstein mit ι Teil Zement und einer geringen Menge Magnesia (etwa 2 Prozent des angewendeten Zechsteins) innig mischt, die Mischung mit der erforderlichen Menge Wasser anfeuchtet, so daß sie formbar ist, und in Formen preßt, worauf man die geformten Produkte an der Luft erhärten läßt,The process is expediently carried out in such a way that 4 parts of Zechstein with ι part of cement and a small amount of magnesia (about 2 percent of the applied Zechstein) mixes intimately, moisten the mixture with the required amount of water, so that it is malleable and pressed into molds, after which the molded products are allowed to harden in the air,
Die Masse eignet sich besonders zur Herstellung von Dachziegeln, Dachpfannen, Flur-, Trottoir- und Bekleidungsplatten, Ornamenten sowie Kunststeinen jeder Art, die sich außer durch ihre ungemeine Festigkeit noch durch ihre glatte Oberfläche und Dichte, des Gefüges auszeichnen, so daß sie auch gegen Wasseraufnahme wenig empfindlich sind.The mass is particularly suitable for the production of roof tiles, roof tiles, corridor, Sidewalk and cladding panels, ornaments and artificial stones of all kinds that are outside due to their immense strength and their smooth surface and density, the structure so that they are not very sensitive to water absorption.
