Es sind bereits porige, schwammartige Stoffe, wie z. B. Bimssteinsand, granulierte Schlacke, Raumasche und zerstampfte Ziegelsteine benutzt worden, um im Mörtel mehr Wasser zurückzuhalten, als dies bei gewöhnlichem Sand der Fall sein kann, der in seinen einzelnen Körnchen vollkommen dicht ist, so daß nur die Oberflächen der Sandkörnchen durch anhaftendes Wasser benetzt werdenThere are already porous, sponge-like substances such. B. pumice sand, granulated slag, Space ash and crushed bricks have been used to retain more water in the mortar than is the case with ordinary Sand that is perfectly dense in its individual granules can be the case, so that only the surfaces of the grains of sand are wetted by adhering water
ίο können.ίο can.
Wenn diese Stoffe aber auch im wasserdichten Gefäß befindlich ziemlich beträchtliche Wassermengen aufzusaugen vermögen, so wird davon doch nur sehr wenig zurückgehalten, wenn sie wassersatt, z. B. aus Wasser geschöpft, auf absaugende Unterlage gebracht werden, wie es beim Mauer- und Putzmörtel ja stets der Fall ist. Die einzelnen Poren in den genannten Stoffen sind viel zu groß, als daß sie ihrem vollen Raum nach Wasser zurückhalten könnten; der : größte Anteil des Wassers sickert nicht nur aus den Hohlräumen zwischen den einzelnen Körnchen, sondern auch aus den zu weiten Zellen in den Körnchen selbst ab, weil es von den Wandungen derselben nicht genügend festgehalten wird.But if these substances are also in the watertight container, they are quite considerable Able to absorb amounts of water, very little of it is retained, if you are fed up with water, e.g. B. scooped from water, placed on an absorbent pad as is always the case with masonry mortar and plastering mortar. The individual pores in the substances mentioned are much too big to hold back their full space for water could; the: largest part of the water not only seeps out of the cavities between the individual granules, but also from the too wide cells in the Granule itself, because it is not sufficiently held by the walls of the same will.
Versuche haben ergeben, daß diese Zurückhaltungskraft für Wasser auch bei Stoffen mit verhältnismäßig großen Poren ganz außerordentlich gesteigert wird, wenn man derartige Stoffe zunächst mit Seifenlösungen tränkt und dann wieder trocknet.Tests have shown that this retention force for water also applies to fabrics with relatively large pores is increased quite extraordinarily if you have such First soak fabrics with soap solutions and then dry them again.
Seife macht bekanntlich Kalk- und Zementmörtel wasserdicht und übt diese günstige Wirkung ohne zu weitgehende Abschwächung der Erhärtungsfestigkeit um so besser aus, je allmählicher sie auf das im Mörtel enthaltene Kalkhydrat zur Einwirkung kommt. Der direkte Zusatz von Seifenlösung zum Kalkmörtel wirkt eher schädlich als nützlich, weil zu schnell beträchtliche Mengen von Kalkhydrat in Seifenkalk umgewandelt werden und für den Erhärtungsprozeß verloren gehen. Praktisch hat man deshalb von dieser an sich schon lange bekannten, wasserdichtenden Wirkung der Seife bisher nur sehr wenig Anwendung gemacht.Soap is known to make lime and cement mortars waterproof and this is beneficial Effect without too extensive a weakening of the hardening strength, the better, ever gradually it comes into action on the hydrated lime contained in the mortar. Of the direct addition of soap solution to the lime mortar is more harmful than beneficial, because Too quickly considerable amounts of hydrated lime are converted into soap lime and are lost for the hardening process. Practically, therefore, one has a waterproof one that has been known for a long time Effect of the soap has so far only been used very little.
Das neue Verfahren, dem wesentliche technische Vorteile eigen sind, wird derart ausgeübt, daß porige, schwammige Stoffe mit warmer, tunlichst angereicherter Seifenlösung getränkt und dann getrocknet werden. Schon beim Tränken haftet die Seifenlösung nicht nur an der Oberfläche der einzelnen Körnchen bedeutend zäher wie reines Wasser, sondern sie wird auch überall an der Oberfläche in den einzelnen Zellen festgehalten, so daß, wenn hinterher die Trocknung erfolgt, feste Seife auf einem überaus großen Oberflächenraum gleichmäßig abgelagert ist.The new procedure, which has significant technical advantages, is carried out in such a way that that porous, spongy fabrics are soaked in warm, enriched soap solution if possible and then dried. Nice When soaking, the soap solution not only adheres to the surface of the individual granules significantly more viscous than pure water, but it will also be everywhere on the surface held in the individual cells, so that when the drying takes place afterwards, solid Soap is evenly deposited on an extremely large surface area.
Wenn diese Zuschlagmasse dem Mörtel zugemischt wird und hierbei wieder mit Wasser in Berührung kommt, so wird solches die Seife nur sehr allmählich lösen, weil kaltes Wasser weit langsamer lösend einwirkt als warmes. Das Wasser wird, selbst wenn derartiger Mörtel auf stark poröse Unterlage gebracht ist, weit besser in dem Mörtel zurückgehalten, als dies sonst der Fall sein würde, so daß es tatsächlich den Mörtel vor zu schneller Austrocknung schützt und die Quali-When this aggregate is mixed with the mortar and again with water comes into contact, then this will only dissolve the soap very gradually, because it is cold Water dissolves much more slowly than warm water. The water becomes, even if such The mortar is placed on a highly porous base, much better retained in the mortar, than would otherwise be the case, so that it actually protects the mortar from drying out too quickly and improves the quality
tat desselben hinsichtlich der Erhärtungsfestigkeit wesentlich verbessert.did the same with regard to the hardening strength significantly improved.
Die dem Mörtel durch diesen Zuschlag zugeführte Seife kann dabei nur sehr allmählich mit dem Kalkhydrat in Berührung kommen, weil das auch in die porigen Körnchen der Zuschlagmasse eindringende Wasser zwar allmählich die darin an den Oberflächen der Zellen abgelagerte Seife löst, aber doch rechtThe soap added to the mortar by this addition can only be very gradual come into contact with the hydrated lime, because that is also in the porous granules of the Aggregate penetrating water gradually increases in it on the surfaces of the Soap loosens cells deposited, but it does
ίο beträchtliche Zeit hindurch in diesen Zellen zurückgehalten werden kann. Erst sehr allmählich, wenn der Austrocknungsprozeß des Mauerwerks mehr und mehr fortschreitet, wird diese aus den Zellen gelöste Seife mit Kalkhydrat in Verbindung kommen, welches noch nicht in kohlensauren Kalk übergeführt ist, so daß sich Seifenkalk noch bilden kann. Ein derartiger Mörtel wird demnach nicht sofort vollkommen wasserdicht, sondern er hat den großen Vorteil, daß auch nach seiner schon oberflächlichen Erhärtung Regenwasser allmählich zutreten und immer wieder neue Kalkmengen in Wanderung setzen kann, so daß Gelegenheit geboten ist, durch sehr allmähliche Umsetzung des Kalkhydrates, teils in kohlensauren Kalk, teils in fettsauren Kalk, die günstigsten Bedingungen herbeizuführen, unter denen Mörtel nicht nur allmählich vollkommen dicht werden, sondern auch die erreichbar größte Erhärtung erfahren kann.ίο in these cells for a considerable time can be withheld. Only very gradually when the Masonry progresses more and more, this soap is loosened from the cells with it Hydrated lime come into contact, which has not yet been converted into carbonate of lime so that soap lime can still form. Such a mortar will therefore not Immediately completely waterproof, but he has the great advantage that even after his already superficial hardening rainwater gradually enter and keep getting new Can set amounts of lime in migration, so that the opportunity is offered by very gradual Implementation of the hydrated lime, partly in carbonate of lime, partly in fatty acid lime, To bring about the most favorable conditions under which mortar is not just gradually perfect become tight, but can also experience the greatest possible hardening.
