Description
<Desc/Clms Page number 1>
Verfahren zur Herstellung von Kunststeinen.
Wird Lehm mit einer 20. bis 30%igen Säurelösung (z. B. Salzsaure oder Schwefelsäure) zerknetet, in Formen gepresst und an der Luft langsam und vollständig getrocknet, so ergibt dies ein dichtes und festes Material, das nur geringe Sprödigkeit besitzt, sich in Wasser nicht auflöst und frostbeständig ist. Die Härte ist etwa diejenige der Handschlag-
EMI1.1
lässt sich auch mit einer Säge schneiden.
Zur Herstellung dieses Materiales verfährt man beispielsweise wie folgt :
Der trockene, fein gemahlene Lehm wird mit einer 20- bis 30%igen Säurelösung angerührt, durchgeknetet und sodann einige Stunden sich selbst überlassen, bis die Masse die erforderliche Konsistenz besitzt, um in Formen gepresst werden zu können.
Das geformte Produkt wird sodann auf freistehenden Gerüsten einer langsamen Trocknung überlassen.
Auf I kg mageren, gewöhnlichen, gelben Lehms, wie er sich meistens unter der Humusschichte der Felder vorfindet, sind beiläufig 320 g 30%iger Säurelösung notwendig, um das Verfahren durchzuführen.
Bei fettem dunklem Letteniebm, bei wachen) die Säure starkes Aufbrausen bewirkt.
EMI1.2
Dasselbe Material kann in frisch angerührtem und verdünutem Zustande auf ganz gleiche Weise wie Mörtel als Bindemittel benutzt werden.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Process for the production of artificial stones.
If clay is kneaded with a 20 to 30% acid solution (e.g. hydrochloric acid or sulfuric acid), pressed into molds and slowly and completely dried in the air, this results in a dense and solid material that is only slightly brittle does not dissolve in water and is frost-resistant. The hardness is roughly that of the handshake
EMI1.1
can also be cut with a saw.
To produce this material, you proceed as follows, for example:
The dry, finely ground clay is mixed with a 20 to 30% acid solution, kneaded and then left for a few hours until the mass has the required consistency to be pressed into molds.
The molded product is then left to dry slowly on free-standing scaffolds.
On 1 kg of lean, ordinary, yellow loam, which is usually found under the humus layer of the fields, 320 g of 30% acid solution are necessary to carry out the process.
In the case of fat, dark Letteniebm, when awake) the acid causes a strong effervescence.
EMI1.2
The same material, freshly mixed and diluted, can be used as a binding agent in exactly the same way as mortar.
