Description

Verfahren zur Herstellung eines Traßzementes. Die bekannten Traßzernente bestehen aus gemahlenem Traß und gebranntem, Kalk. Sie sind ebensowenig wie andere Zemente befähigt, ungereinigten oder ungewaschenen Erdaushub, so wie er anfällt, also-beispielsweise lehmartigen unsortierten Sand oder Kies, Gartenerde .u. dgl. zu binden.Process for the production of a trass cement. The well-known Traßzernente consist of ground trass and burnt lime. They are no more than others Cement enables uncleaned or unwashed excavated earth, as it occurs, So-for example loamy unsorted sand or gravel, garden soil .u. like to tie.

Demgegenüber bezweckt die vorliegende Erfindung vor allem die Herstellung eines Traßzementes, welcher nicht allein die Eigenschaft hat, ungereinigten oder ungewaschenen Erdaushub abzubinden., sondern auch dem damit erzeugten Beton eine Druckfestigkeit zu verleihen, welche mit Traßzement zu erzielen bis heute nicht möglich war. Um die gleiche Druckfestigkeit wie bisher zu erreichen, genügt infolgedessen eine geringere Menge des nach dem vorliegenden Verfahren hergestellten Traßzementes, wobei außerdem an Stelle von gewaschenem Sand und Kies ungereinigter Erdaushub tritt oder treten kann. ° Das Verfahren besteht im wesentlichen darin, daß man dein aus gemahlenem Traß und gebranntem Kalk hergestellten Zement einen Zuschlag beigibt, welcher aus einem Alkali mit Holzasche (deren wirksamer Teil Pottasche ist) oder Wasserglas oder aber aus Chlormagnesium und Magnesia besteht.In contrast, the present invention aims primarily to manufacture a trass cement, which does not only have the property, uncleaned or to bind unwashed excavated earth, but also to the concrete produced with it To give compressive strength, which can not be achieved with trass cement until today was possible. As a result, it is sufficient to achieve the same compressive strength as before a smaller amount of the trass cement produced by the present process, In addition, uncleaned excavated earth takes the place of washed sand and gravel or can kick. ° The process essentially consists in getting your from adds a surcharge to cement made from ground trass and quick lime, which of an alkali with wood ash (the effective part of which is potash) or Water glass or made of chlorine magnesium and magnesia.

Hierbei kann man beispielsweise folgendes Mischungsverhältnis anwenden: 15 Gewichtsteile Traß, 15 Gewichtsteile Kalk, o,5 Gewichtsteile Natronlauge und 2 Gewichtsteile Wasserglas oder Holzasche.For example, the following mixing ratio can be used here: 15 parts by weight of trass, 15 parts by weight of lime, 0.5 parts by weight of caustic soda and 2 parts by weight of water glass or wood ash.

Die Vermischung dieses Traßzementes mit dem Füllstoff erfolgt in bekannter Weise mit dem entsprechenden Zusatz von Wasser. Dabei kann das Mischungsverhältnis` des Zerrentes zum Füllstoff etwa i zu q. bis i zu 5 gewählt werden.The mixing of this trass cement with the filler takes place in a known manner Way with the appropriate addition of water. The mixing ratio can be used of the distortion to the filler about i to q. up to i up to 5 can be chosen.

Das Mischungsverhältnis der einzelnen Stoffe kann ,sich natürlich je nach Art und Zweck der herzustellenden Bauten nach Bedarf ändern.The mixing ratio of the individual substances can vary, of course change as required depending on the type and purpose of the structures to be constructed.
