Description

Verfahren zum Herstellen von Kunststeinen, insbesondere zur Abschirmung gegen Röntgenstrahlen Zum Abschirmen gegen Röntgenstrahlen sind Kunststeine bekannt, die aus einem Schwerspat enthaltenden Beton hergestellt sind. Diese Kunststeine werden in der Weise hergestellt, daß Schwerspat mit einer geringen Menge Zemnent zu einem Beton von hohem spezifischen Gewicht verarbeitet wird. Da der hierbei verwendete Schwerspat als Mineral besonders gewonnen und auf die zur Verwendung bei der Betonherstellung erforderliche Körnung gebracht werden muß, so ist die Herstellung derartiger Kunststeine verhältnismäßig kostspielig.Process for the production of artificial stones, in particular for shielding against X-rays Artificial stones are known for shielding against X-rays, which are made of a concrete containing heavy spar. These artificial stones are made in such a way that barite with a small amount of cement is processed into a concrete of high specific weight. Since the Barite as a mineral especially obtained and used in concrete production required grain size must be brought, so is the production of such artificial stones relatively expensive.

Germäß der Erfindung kann ein insbesondere zum Abschirmen gegen Röntgenstrahlen geeigneter Kunststein besonders preiswert dadurch erhalten werden, daß bestimmte, bei der Metallgewinnung anfallende, barythaltige Schlacken für die Herstellung dieser Kunststeine verwendet werden. Desonders geeignet hierfür sind die bei der Bleigewinnung anfallenden Schlacken, da diese je nach ihrer Herkunft einen hohen Gehalt an Barvt aufweisen, der bekanntlich eine besonders wirksame Aibschirmung gegen Röntgenstrahlen schafft. Eine derartige Schlacke wird auf die für die Herstellung voni Kunststeinen nötige Körnung oder Kleinstückigkeit gebracht und mit einer geringen Menge, Z. B. etwa 6%, Zement vermischt. -D,ie-ge 'Masse kann dann wie bci der Herstellun I - von Kunststeinen aus Beton in breiiger oder plastischer Konsistenz in Formen gefüll, werden und wird vorztib-sweise, wie an sicli bekannt, durch Rütteln verdichtet.According to the invention, an artificial stone which is particularly suitable for shielding against X-rays can be obtained particularly inexpensively by using certain barite-containing slags from the extraction of metal for the production of these artificial stones. Particularly suitable for this are the slag produced during lead extraction, since, depending on their origin, they have a high content of Barvt, which is known to provide a particularly effective shield against X-rays. Such a slag is brought to the grain size or small pieces required for the production of artificial stones and mixed with a small amount, e.g. about 6%, cement. -D, ie-ge 'mass may then as the bci Herstellun I - filled j of artificial stones of concrete in pasty or plastic consistency in molds and is vorztib-sweise, as known per Sicli, compacted by shaking.

Die Erfindung ermöglicht eine wirtschaftliche Verwendung der insbesondere bei der Bleigewinnung anfallenden Schlacke, die bisher- zu diesem Zweck nicht ausgenutzt wurde. Da -,es sich hierbei nin ein ausgesprochenes Abfallermugnis handelt, so können b clie Kunststeine nach deili neuen Verfahren ganz erheblich billiger hergestellt werden als unter Verwendungiii von Schwerspat.The invention enables an economical use of the slag which occurs in particular in lead extraction and which has not previously been used for this purpose. Because - it this is a pronounced nin Abfallermugnis so b clie artificial stones can be produced considerably cheaper than under Verwendungiii of barite according deili new procedures.
