Claims (1)

AT 397 650 B Die Erfindung betrifft ein Dämmaterial bestehend aus Sand Flugasche und Bentonit. Bekannt ist ein Verdämmungsmaterial zur Wasserdichtmachung von Böden. Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, ein Dämmaterial zu schaffen, welches mit herkömmlichen Betonpumpen gefördert und bei Bedarf unter Druck verpreßt werden kann. 5 Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil des Patentanspruches beschriebenen Merkmale gelöst. Durch den Zusatz von Bentonit wird das Schwinden beim Austrocknen verhindert. An einer Probe des erfindungsgemäßen Materials wurde eine Untersuchung auf Umweltverträglichkeit durchgeführt. Es zeigte sich, daß gemäß der Analysenwerte alle Parameter des Eluates von dem erfin-io dungsgemäßen Materials unter den in der ÖNORM S 2072 angeführten Grenzwerten der Eluatklasse Ib ( EK Ib )liegen. Das erfindungsgemäße Dämmaterial übt demnach keine nachteilige Beeinflussung des Grundwassers aus. Die genannte Dämmasse kann verwendet werden zum Verfüllen von unterirdischen Hohlräumen jeder is Art, wie etwa aufgelassene Stollen, Bunker oder Kanäle. Weiters bei Versorgungs- oder Entsorgungsleitungen zum Verfüllen von verbleibenden Hohlräumen oder bei verlegten Schutzrohren, in welchen die Mediumrohre eingezogen wurden. Bei Bedarf kann das erfindungsgemäße Material mit Wasser ausgespült werden, wobei auch die Zusammensetzung des Materials nach Bedarf in den Mengen verändert werden kann. 20 Patentansprüche 1. Dämmaterial aus Sand, Flugasche und Bentonit zum Verfüllen von Hohlräumen, dadurch gekennzeichnet, daß es aus 1.800 kg Sand, mit einer Korngröße von 0 bis 8 mm, 50 kg Braunkohlenfluga-25 sehe, 50 kg Bentonit und 250 bis 350 Liter Wasser besteht. 50 2 55AT 397 650 B The invention relates to an insulating material consisting of sand, fly ash and bentonite. An insulation material for waterproofing floors is known. The present invention has for its object to provide an insulating material which can be conveyed with conventional concrete pumps and pressed under pressure if necessary. 5 According to the invention this object is achieved by the features described in the characterizing part of the patent claim. The addition of bentonite prevents shrinkage when drying out. An environmental compatibility test was carried out on a sample of the material according to the invention. It was found that according to the analysis values, all parameters of the eluate from the material according to the invention are below the limit values of the eluate class Ib (EK Ib) specified in ÖNORM S 2072. The insulating material according to the invention therefore does not adversely affect the groundwater. The mentioned insulating material can be used to fill any type of underground cavities, such as abandoned tunnels, bunkers or channels. Furthermore, with supply or disposal lines for filling remaining cavities or with installed protective pipes in which the medium pipes were drawn. If necessary, the material according to the invention can be rinsed out with water, and the composition of the material can also be changed in amounts as required. 20 claims 1. Insulating material made of sand, fly ash and bentonite for filling cavities, characterized in that it consists of 1,800 kg of sand, with a grain size of 0 to 8 mm, 50 kg of brown coal Fluga-25, 50 kg of bentonite and 250 to 350 liters There is water. 50 2 55
