Description

Verfahren zur Herstellung von Steinen aus Schlacken aller Art. Die Erfindung betrifft ein Verfahren zur Herstellung von Steinen aus Schlacken aller Art. Es hat sich überraschenderweise herausgestellt, daß Schlacken aller Art, wie beispielsweise Hochofenschlacken, sich außer zur Herstellung von Zement in hervorragender Weise auch zur Herstellung von Steinen für Bauzwecke o. dgl. eignen, falls der trockenen, mehr oder weniger fein gemahlenen und auch ungetrockneten Schlacke ungebrannter Gips, wie er in der Natur vorkommt, oder als wasserhaltiger oder wasserfreier Gips (Anhydrit) zugesetzt wird. Der Mischung wird für das leichtere Pressen der Steine Wasser zugegeben. Die- bei Ausübung des Verfahrens erreichte bedeutende Festigkeit der Steine kann auch noch dadurch gesteigert «-erden, daß die Schlacke in feuchtem oder in trockenem Zustande mit Gips bzw. Anhydrit vermahlen wird.Process for the production of stones from slag of all kinds. The Invention relates to a method for making bricks from slag of all Art. It has surprisingly been found that slags of all kinds, such as for example blast furnace slag, except for the production of cement in excellent Way also for the production of stones for building purposes or the like. Suitable, if the dry, more or less finely ground and undried slag of unfired Gypsum as it occurs in nature, or as water-based or anhydrous gypsum (Anhydrite) is added. The mixture is used for easier pressing of the stones Water added. The significant strength achieved in the practice of the process the stone can also be increased by the fact that the slag is in a moist or is ground in the dry state with gypsum or anhydrite.

Ebensogut wie ungemahlene kann auch gernahlene Schlacke verwendet werden, auch kann statt der trockenen Schlacke feuchte Schlacke zusammen mit Gips vermahlen werden. Ferner kann die Mischung von Schlacke und Gips Zuschläge mit Alkalicharakter erhalten, also beispielsweise Soda, Kalziumoxyd usw., Zuschläge, die bei der Herstellung von Zement, beispielsweise aus Anhydrit, bereits bekannt sind.Grinded slag can be used just as well as unground slag Instead of dry slag, moist slag together with plaster of paris can also be used be ground. Furthermore, the mixture of slag and plaster of paris can produce aggregates with an alkaline character received, so for example soda, calcium oxide, etc., supplements that are used in the production of cement, for example from anhydrite, are already known.

Anderen Steinen gegenüber, beispielsweise Kalksandsteinen, hat das vorliegende Verfahren den bedeutenden Vorteil, daß eine Härtung der Steine fortfällt und daß das Verfahren sich billiger und wirtschaftlicher gestaltet. Dazu kommt außerdem noch, daß die Steine auch bei Verwendung von ungeznahlener Schlacke bereits bedeutende Festigkeiten aufweisen. Wird gemahlene Schlacke verwendet, so genügt erfahrungsgemäß schon Grießfeinheit, um eine bei weitem höhere Festigkeit zu erzielen, als erforderlich ist.Compared to other stones, for example sand-lime bricks, this has that present processes have the significant advantage that there is no hardening of the stones and that the process is cheaper and more economical. In addition, there is nor that the stones are already significant even with the use of innumerable slag Have strengths. Experience has shown that if ground slag is used Even semolina fineness in order to achieve a far higher strength than necessary is.
