Abstract

The extrusions are made from a mixt. contg. cement, organic and/or glass fibres, water, at least one agent (I) aiding extrusion, and water adsorbing aggregate consisting of chalk and/or diatomite and/or talc. The organic fibres are pref. polymer fibres, esp. polythene- and/or polypropylene fibres. A pref. mixt.(A) contains 40 kg Portland- or hydraulic- cement, 8 kg chalk, 4 kg talc, esp. type IMI-R6S, 13 kg water, and 1.3 kg fibres as above; another pref. mixt. (B) contains 40 kg cement, 2 kg diatomite, 11 kg water and 1.2 kg fibres. The third pref. mixt.(C) contains 40 kg cement, 2 kg diatomite, 2 kg talc, 23 kg water, and 1.2 kg fibres. An amorphous diatomite is pref. used in the mixts. None of the mixts. contain asbestos fibres, which are harmful to health. The mouldings are sufficiently rigid immediately after extrusion so they do not lose their shape until hardening is complete, but they contain sufficient water to ensure complete hardening. The mixts. are used in conventional extrusion machines, e.g. to make panels, rods or pipes.

Titel: Verfahren zum Strangpressen von formbeständigen,Title: Process for the extrusion of dimensionally stable,

härtbaren Zementformkörpern Verfahren zum Strangpressen von formbeständigen, härtbaren Zementformkörpern üie Erfindung betrifft ein Verfahren zum Strangpressen von formbeständigen, härtbaren Zementformkörpern, bei dem ein Gemisch aus Zement, aus wenigstens einem Extrudierungshilfsmittel, aus wasseradsorbierenden Zuschlagstoffen sowie aus Wasser mit Hilfe eines extruders, z.B. mit Hilfe eines üblichen Kolben- oder Schneckenextruders extrudiert wird. hardenable cement moldings Method of extrusion of dimensionally stable, hardenable cement moldings üie invention relates to a method for the extrusion of dimensionally stable, hardenable cement moldings, in which a Mixture of cement, of at least one extrusion aid, of water-absorbing Aggregates as well as from water with the help of an extruder, e.g. with the help of a conventional piston or screw extruder is extruded.

Derartige Verfahren sind an sich bekannt und werden beispielsweise zum Herstellen von platten-, stangen- oder rohrförmigen Formkörpern verwendet.Such methods are known per se and are for example used for the production of plate, rod or tubular shaped bodies.

in Problem bei diesen Verfahren besteht grundsätzlich darin, daß das Gemisch bzw. die t-iasse nach den extrudieren eine ausreichende Menge an Wasser enthalten muß, um ein vollständiges Abbinden bzw. Aushärten des hydraulischen Zementes sicherzustellen. Weiterhin ist es bei Verfahren zum Extrudieren bzw. zum Strangpressen von Zementformkörpern erforderlich, daß das Gemisch trotz des zum Abbinden bzw. Aushärten des hydraulischen Zements erforderlichen Wasseranteils eine möglichst steife Masse bildet, damit sich die Formkörper nach dem Extrudieren und bis zum Abbinden bzw.The fundamental problem with these methods is that the Mixture or the t-cup after extruding a sufficient amount of water must contain to a complete setting or hardening of the hydraulic cement to ensure. It is also used for extrusion or extrusion processes of cement moldings, it is necessary that the mixture, in spite of the setting or Hardening of the hydraulic cement required water content as possible Stiff mass forms, so that the moldings after extrusion and up to Setting or

Aushärten des hydraulischen Zements in ihrer Formgebung nicht oder nur unwesentlich verundern.The hydraulic cement does not or does not harden in its shape change only insignificantly.

Bei bekannten Verfahren wird dieses Problem dadurch gelöst, daß dem Gemisch neben Extrudierungshilfsmittels und/oder Gleitmitteln, wie beispielsweise Tylose, Polyglykol und/oder Melment, Asbestfasern beigegeben werden, die aufgrund ihrer röhrchenförmigen Struktur Wasser adsorbieren und bei hohem Druck wieder abgeben. Hierdurch ist einerseits sichergestellt, daß das Gemisch nach dem Aushärten eine genügende Steifigkeit aufweist und anderes seits eine genügende enge an Wasser enthält, um ein vollständiges Abbinden bzw. Ausharten des hydraulischen Zementes sicherzustellen. tin Verfahren zum Strangpressen von formbeständigen, härtbaren Zementformkörpern unter Verwendung von Asbestfasern und Extrudierungs-Hilfsmitteln ist beispielsweise in der DE-AS 14 71 254 beschrieben.In known methods, this problem is solved in that the Mixture in addition to extrusion auxiliaries and / or lubricants, such as Tylose, polyglycol and / or melment, asbestos fibers are added due to Their tubular structure adsorb water and release it again at high pressure. This ensures on the one hand that the mixture after curing a has sufficient rigidity and, on the other hand, contains a sufficient amount of water, to ensure complete setting or hardening of the hydraulic cement. tin Process for the extrusion of dimensionally stable, hardenable cement moldings under Use of asbestos fibers and extrusion aids is described in DE-AS 14 71 254, for example.

Obwohl die bei bekannten Verfahren verwendeten Gemische aus Zement, aus dem Extrudierungshilfsmittel, aus Asbestfasern und Wasser zu guten Ergebnissen fuhren und nach dem Aushärten bzw. Abbinden des hydraulischen Zements Formkörper mit hoher Festigkeit liefern, besteht nach den neuesten Erkenntnissen ein erheblicher Nachteil der bekannten Verfahren bzw. der bei diesen Verfahren verwendeten Gemische in der gesundheitsschädlichen Wirkung der Asbestfasern. Gesundheitsschädliche Folgen sind dabei nicht nur bei der Verarbeitung der bekannten Gemische beim Herstellen von Zementformkörpern, sondern auch bei der späteren Verarbeitung bzw. Bearbeitung der ausgehärteten Zementformkörper zu erwarten.Although the mixtures of cement used in known processes, from the extrusion aid, from asbestos fibers and water for good results and after the hydraulic cement has hardened or set, molded bodies deliver with high strength, there is, according to the latest findings, a considerable Disadvantage of the known processes or the mixtures used in these processes in the harmful effects of asbestos fibers.
