Feuerfeste nischungen mit hydraulischer AbbindungRefractory niches with hydraulic setting

Die vorliegende Erfindung betrifft neue feiierfeste, spritzbare Mischungen auf der Basis von Zement und inerten Zuschlagstoffen.The present invention relates to new celebrations, sprayable mixtures based on cement and inert aggregates.

In der Hauptpatentanmeldung wurden neue feuerfeste Mischungen mit hydraulischer Abbindung beschrieben, die neben einem feuerfesten Zuschlag bestehen aus:New refractories were included in the main patent application Mixtures with hydraulic setting are described which, in addition to a refractory aggregate, consist of:

Es hat sich jetzt erwiesen, daß es bei Verwendung von Gemischen, welche dieselben Grundbestandteile enthalten, möglich ist, spritzbare feuerfeste Betonsorten herzustellen, die ausgezeichnete mechanische Eigenschaften besitzen. Es wird daran erinnert, daß ein feuerfester Beton .als spitzbar bezeichnet ΐί/ird, wenn er, durch Spritzen - beispielsweise mittels eines pneumatischen Strahlrohrs - aufgebracht, solche Haftungseigenschaften auf v/eist, daß die durch Abprall entstehenden Verluste gering sind und beispielsweise im Falle des Aufspritzens auf eine vertikale Wand weniger als 15 .'° betragen.It has now been found that using mixtures which contain the same basic components it is possible to produce sprayable refractory concretes which have excellent mechanical properties. It should be remembered that a refractory concrete. Als spitzbar ΐί / ird, if it, applied by spraying - for example by means of a pneumatic jet pipe - has such adhesion properties that the losses caused by rebound are low and, for example, in the case of the spraying on a vertical wall is less than 15. '°.

Die Erfindung betrifft also neue feuerfeste, spitzbare irischungen, dadurch gekennzeichnet, daß sie: - The invention thus relates to new refractory, sharpenable irishments, characterized in that they:

wenigstens 5 bis 13 Gewichtsteile eines hydraulischen Zements,at least 5 to 13 parts by weight of a hydraulic one Cement,

und wenigstens 78 "bis 92 Gewichtsteile eines feuerfesten Zuschlagstoffes enthalten.and at least 78 "to 92 parts by weight of a refractory Contain aggregate.

Die Versuche haben gezeigt, daß solche feuerfesten Mischungen zusätzlich zu ihren bemerkenswerten mechanischen Eigenschaften einen sehr geringen Abprall aufweisen, wenn sie im Aufspritzverfahren verwendet werden.The experiments have shown that such refractory mixtures, in addition to their remarkable mechanical Properties have very low rebound when used in the injection molding process.

Die Erfindung wird durch das nachstehende, nicht einschränkende Beispiel erläutert. In diesem Beispiel werden die Eigenschaften des erfindungsgemäßen Betons mit denen eines gegenwärtig bekannten und verwendeten, herkömmlichen, feuerfesten Betons verglichen. Bestandteile (in Erfindungsgemäße Ein gegen--Gewichtsteilen) feuerfeste form- wärtigerThe invention is illustrated by the following non-limiting example. This example will be the properties of the concrete according to the invention with those of a currently known and used, conventional, refractory concrete compared.
