Description

Herstellung von Leichtbeton Es ist bekannt, organische Faserstoffe, die als Zuschlagstoffe für Leichtbeton verwendet werden sollen, vor der Verarbeitung mit den verschiedensten Mitteln, wie Kalk, Zement, Wasserglas, Latex, Leim, Bitumenemulsion, Kaltasphalt, Steinmehl, Kohlenstaub, Ruß, Ton, Lehm und anderen Stoffen, vorzubehandeln, zu mineralisieren oder zu imprägnieren.Production of lightweight concrete It is known to use organic fibers, which are to be used as aggregates for lightweight concrete, before processing with a wide variety of means, such as lime, cement, water glass, latex, glue, bitumen emulsion, Cold asphalt, stone powder, coal dust, soot, clay, loam and other materials to be pretreated, to mineralize or impregnate.

Alle diese Verfahren beanspruchen jedoch einen mehr oder minder großen Arbeitsaufwand und bedingen mehrere zeitlich voneinander getrennte Arbeitsgänge. Von dieser Unwirtschaftlichkeit abgesehen, werden aber auch die an solche Leichtbetone gestellten Anforderungen meist nur zum Teil erfüllt.However, all of these methods require a more or less large one Workload and require several separate work steps. Apart from this inefficiency, there are also those of such lightweight concretes The requirements set are mostly only partially met.

Das nachstehend beschriebene Verfahren beruht auf neuen Erkenntnissen und gestattet, alle Arbeitsgänge ohne zeitliche Trennung durchzuführen.The procedure described below is based on new knowledge and allows all operations to be carried out without any time separation.

Neu ist, daß man den bei der Aufbereitung von Hochofenschaumschlacke oder Hüttenbims anfallenden Staub nach dem Anmachen mit Wasser zum Mineralisieiren organischer Faserstoffe verwenden kann. Diese so vorbehandelten organischen Faserstoffe können sofort durch Vermischen mit einem gebräuchlichen Bindemittel zu Leichtbeton verarbeitet werden.What is new is that it is used in the processing of blast furnace foam slag or dust from pumice after mixing with water for mineralization of organic fibers can use. These pre-treated organic fibers can be made into lightweight concrete immediately by mixing with a common binding agent are processed.

Neu ist auch, daß man; wenn Hüttenbims, Hüttenbimssand oder andere Sande mit dem Staub von Hüttenbims oder Schaumschlacke vorbehandelt werden, diesem Gemisch organische Faserstoffe zusetzen kann, @diedann keiner Vorbehandlung bedürfen, um sofort zu Leichtbeton verarbeitet zu werden. Diese so vorbehandelten Zuschlagstoffe können sofort durch Vermischen mit einem gebräuchlichen Bindemittel zu Leichtbeton verarbeitet werden. Zur Erzielung farbiger Leichtbetone kann Ruß oder eine andere kalkechte Farbe beigemischt werden.What is also new is that one; if pumice, pumice sand or other Sands are pretreated with the dust of smelting pumice or foamed slag, this Can add organic fibers to a mixture, @that then do not require any pretreatment, to be processed immediately into lightweight concrete. These aggregates pretreated in this way can immediately processed into lightweight concrete by mixing with a common binding agent will. In order to achieve colored lightweight concrete, soot or another non-calcareous material can be used Color can be added.
