Description

Verfahren zur Herstellung von Bauelementen aus Beton, Kunststein, Steinholz oder ähnlichen Baumaterialien in Verbindung mit metallischem Blei Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Bauelementen in Form von Platten, Blöcken od. dgl., welche aus Beton, Kunststein, Steinholz usw. mit Einschlüssen oder Beimengungen von metallischem Blei zur Erzielung strahlungsschwächender, strahlungshemmender bzw. -absorbierender Wirkung bestehen. Durch die Erfindung wird eine weitere Ausgestaltung und Verbesserung der im Patent 1066123 geschützten Erfindung bezweckt.Process for the production of construction elements from concrete, artificial stone, Stone wood or similar building materials in connection with metallic lead Die The invention relates to a method for producing components in the form of plates, blocks or the like. Which are made of concrete, artificial stone, stone wood, etc. with Inclusions or admixtures of metallic lead to achieve radiation-weakening, radiation-inhibiting or radiation-absorbing effect exist. Through the invention a further embodiment and improvement of the invention protected in patent 1066123 aims.

Gemäß dem Hauptpatent bestehen die dem Baumaterial beigemengten Stoffe aus Bleispänen oder -teilchen. Dabei soll eine besonders gleichmäßige und innige Verbindung zwischen dem Baumaterial und dem beigemengten Blei erzielt werden. Die Vermischung muß sehr sorgfältig, gleichmäßig und in feiner Verteilung erfolgen. Hierbei wird im allgemeinen zunächst eine Grundmasse hergestellt, welche dann zur Herstellung beliebiger Bauelemente dient oder zum Verputzen, zur Ausfüllung von Fugen usw. verwendet werden kann. Es wurde nun gefunden, daß es möglich ist, das Verfahren zur Herstellung solcher Grundmassen bzw. Bauelemente oder Putz- und Dichtungsmaterialien noch einfacher und wirtschaftlicher als bisher zu gestalten.According to the main patent, the substances added to the building material exist from lead chips or particles. It should be particularly even and intimate Connection between the building material and the added lead can be achieved. the Mixing must be done very carefully, evenly and finely. In this case, a base material is generally first produced, which is then used for Production of any components is used or for plastering, for filling Grout etc. can be used. It has now been found that it is possible to do that Process for the production of such base materials or components or plastering and sealing materials even easier and more economical than before.

Die Erfindung besteht nun im wesentlichen darin, daß natürliche Mineralien, die einen gewissen Prozentsatz an Blei als stark strahlungshemmendes Element enthalten, auf irgendeine Weise zerkleinert oder zermahlen, gegebenenfalls noch durch Mischung homogenisiert und unmittelbar als Grundmasse für eine Bindung mit Zement oder sonstigen Bindemitteln, wie z. B. Kunstharz, verwendet werden. Eine solche Grundmasse liefert einen sehr geeigneten Baustoff für Bauelemente gemäß der Erfindung bzw. bildet eine entsprechende Masse zum Verputzen, zur Auskleidung von Fugen in Strahlenschutzwänden oder -decken. Es hat sich gezeigt, daß die im allgemeinen mit Schwermetallen in natürlichen Mineralien vorkommenden Stoffe, wie insbesondere Kieselsäure, gut für eine Bindung mit Zement, Kunstharz oder sonstigen Bindemitteln. geeignet sind, so daß sie zugleich das Grundmaterial für den strahlungshemmenden Beton, Kunststein usw. oder einen entsprechenden Putz bilden.The invention consists essentially in the fact that natural minerals, which contain a certain percentage of lead as a strong radiation-inhibiting element, crushed or ground in some way, possibly also by mixing homogenized and immediately used as a base material for bonding with cement or other Binders, such as B. synthetic resin can be used. Such a matrix provides a very suitable building material for building elements according to the invention or forms a Appropriate mass for plastering, for lining joints in radiation protection walls or blankets. It has been shown that those generally associated with heavy metals in natural minerals, such as silica in particular, good for a bond with cement, synthetic resin or other binders. are suitable so that they are also the basic material for the radiation-inhibiting concrete, artificial stone etc. or form a corresponding plaster.

Durch die Erfindung wird erreicht, daß auch Mineralien mit geringem Schwermetallgehalt, deren Verhüttung wirtschaftlich nicht lohnend ist, für die Herstellung von Strahlenschutz-Bauelementen od. dgl. im Sinn der Erfindung ausgenutzt werden können. Die Verwendung von in der Natur vorkommenden schwermetallhaltigen Gesteinen als Grundmasse ergibt außerdem ein Baumaterial, in welchem die gegen Strahlung besonders wirksamen Bestandteile, nämlich Blei, chemisch sehr stabil gebunden und mechanisch bei entsprechender Zerkleinerung und gegebenenfalls Durchmischung sehr gleichmäßig verteilt sind, worauf es erfindungsgemäß in hohem Maße ankommt.The invention achieves that minerals with a low Heavy metal content, the smelting of which is not economically viable, for production of radiation protection components or the like. Be exploited within the meaning of the invention can. The use of naturally occurring rocks containing heavy metals as a base material there is also a building material in which the resistance to radiation is particularly good active components, namely lead, chemically very stable and mechanically bound very evenly with appropriate comminution and, if necessary, mixing are distributed, which is very important according to the invention.

Gemäß einer weiteren Ausgestaltung der Erfindung kann es zweckmäßig sein, die durch das Zermahlen aus den Mineralien erhaltene Grundmasse durch Zugabe konzentrierter, stark strahlungshemmender Stoffe wie insbesondere Schwermetallverbindungen oder auch reiner Metalle in pulverisierter Form in. ihren Strahlenschutzeigenschaften zu verbessern. Zur Anreicherung in diesem Sinne kann der Grundmasse auch Schwerspat beigefügt werden.According to a further embodiment of the invention, it can be expedient be the base mass obtained from the grinding of the minerals by adding concentrated, highly radiation-inhibiting substances such as heavy metal compounds in particular or pure metals in powdered form in their radiation protection properties to improve. For enrichment in this sense, the basic mass can also be heavy spar attached.

Die Erfindung umfaßt nicht nur das vorstehend beschriebene Verfahren zur Herstellung von Strahlenschutzmassen für Bauzwecke usw., sondern sie erstreckt sich auch auf die unter Verwendung einer solchen Grundmasse hergestellten Baumaterialien, Bauelemente wie insbesondere Bauplatten oder -blöcke sowie auf Putz- und Auskleidungsmaterial für Strahlenschutzzwecke.The invention does not only include the method described above for the production of radiation protection materials for building purposes, etc., but it extends also apply to building materials manufactured using such a base material, Construction elements such as in particular construction panels or blocks and on plaster and lining material for radiation protection purposes.
