Description
Den Gegenstand der Erfindung bildet die Verwendung eines neuen Füll- und Dämmstoffes für Zementmischungen. Als Füll- und Dämmstoffe für solche Zwecke wurden bisher verschiedene organische und anorganische Faserstoffe vorgeschlagen. Es ist unter anderem auch bekannt, in solchen Mischungen Asbestfaser zu verwenden. Die unter Verwendung von Asbestfaser, Zement und Wasser hergestellten Mischungen besitzen jedoch nach dem Erhärten keine ausgeprägt hohe Wärme- und Trittschalldämmung und keine entsprechende Schwundfreiheit. Daher können solche Mischungen ζ. Β. als Estrich nicht verwendet werden.The object of the invention is the use of a new filler and insulating material for cement mixtures. As fillers and insulating materials for such purposes, various organic and proposed inorganic fibers. It is also known, among other things, to use asbestos fiber in such mixtures to use. Made using asbestos fiber, cement and water However, after hardening, mixtures do not have a particularly high level of heat and impact sound insulation and no corresponding freedom from shrinkage. Therefore, such mixtures can ζ. Β. not used as screed will.
Es wurde nun gefunden, daß auf der Basis von Zement hergestellte beliebige Mischungen dann hohe Wärme- und Trittschalldämmung, geringes Gewicht, hohe Elastizität, eine ausgezeichnete glatte Oberfläche und kurze Trockenzeit besitzen, wenn ihnen kunst- und/oder naturkautschukimprägnierte Asbestfaser als Füll- und Dämmstoff zugesetzt wird. Die erwähnten günstigen Eigenschaften kommen insbesondere bei der Verwendung der erfindungsgemäßen Mischung als Unterlagsestrich für die Aufbringung von Bodenbelägen zum Tragen. Nachstehende Gegenüberstellung von Werten eines normalen und eines erfindungsgemäßen Asbest-Zement-Estrichs bringt dies klar zum AusdruckIt has now been found that any mixtures produced on the basis of cement are then high Thermal and impact sound insulation, low weight, high elasticity, an excellent smooth surface and have a short drying time if you use synthetic and / or natural rubber-impregnated asbestos fibers is added as a filler and insulating material. The favorable properties mentioned come in particular when using the mixture according to the invention as an underlay for application of floor coverings for wear. The following comparison of values of a normal and a Asbestos-cement screed according to the invention clearly expresses this

Bei Verwendung von unimprägnierter Asbestfaser nimmt diese das Wasser in sich auf, ergibt eine Quellung mit einem anschließenden starken Schwund beim Trocknen. Bei Verwendung imprägnierter Asbestfaser nimmt diese das Wasser nur oberflächlich auf, gibt es zur Abbildung an den Zement ab, so daß dadurch Hohlräume an Stelle des von der imprägnierten Asbestfaser gehaltenen Wassers entstehen.When using unimpregnated asbestos fiber, it absorbs the water, resulting in a Swelling followed by severe shrinkage when drying. When using impregnated Asbestos fiber only absorbs the water superficially, it gives it to the cement for illustration, see above that this creates cavities in place of the water held by the impregnated asbestos fiber.
