Description

Verfahren zur Herstellung von Zellensteinen Das vorliegende Verfahren bildet besonders eine Neuheit in der Kalksandsteinindustrie. Frische Splitte, die erfindungsgemäß zu Kalksandsteinmassen zugesetzt werden sollen, werden zu diesem Zwecke vorher in überhitzten Dämpfen starker Aufquellung ausgesetzt und in warmem Zustand dem Mischgut bis zu q.0°/, beigemischt. Am besten eignen sich frische Frässplitte von Erlen, Buchen und Eichen. Die starke Aufquellung verhindert ein nachträgliches Wiederausdehnen der Splitte beim Härteverfahren. Infolge der stark vergrößerten Angriffsflächen im Preßling für den Dampf wird der Härteprozeß auch beschleunigt.Method of making cell blocks The present method is particularly a novelty in the sand-lime brick industry. Fresh grit that to be added according to the invention to sand-lime brick masses are to this Purposes previously exposed to strong swelling in overheated vapors and in warm State of the mix up to q.0 ° /, mixed. Fresh chippings are best of alders, beeches and oaks. The strong swelling prevents a subsequent Re-expansion of the chippings during the hardening process. As a result of the greatly enlarged The hardening process is also accelerated in the compact for the steam to attack.

Die Leichtigkeit dieser Zcllenbetonsteine ist sehr erheblich. Ebenso wia bei Zementmörtel zunächst ein erhöhtes Haften an die Außenflächen der wasserabgebenden Splitte stattfindet, tritt (lies auch in der Kalksandsteinindmstrie hinsichtlich des Kalksandgemisches ein. Dadurch wird die Bildung der Zellenwandungen gefördert, und infolge des aus dem Splitt der unmittelbaren Umhüllung reichlicher zugeführten Wassers tritt eine innere festere Schalenbildung ein. Nachträgliches Verspaken der Splitte wird 'durch an sich bekanntes vorheriges Imprägnieren mit desinfizierenden Stoffen vermieden.The lightness of these cellular concrete blocks is very considerable. as well As is the case with cement mortar, there is initially increased adhesion to the outer surfaces of the water-emitting Splitting takes place, occurs (read also in the sand-lime stone industry regarding of the sand-lime mixture. This promotes the formation of the cell walls, and as a result of the more abundantly supplied from the chippings to the immediate envelope Water forms an inner, firmer shell. Subsequent packing of the Chippings are made by impregnating them with disinfectants, which is known per se Substances avoided.
