Description

Verfahren zur Herstellung von betonartigem Material hoher geetigkeit Die Erfindung betrifft ein Verfahren zur Herstellung von betonartigem Material hoher Festigkeit, bei dem nach der Lehre dos Hauptpatentes etwa ?0 % fetter Lehm und 30 % Kalk fein gemahlen und in trockenem Zustand innig vermischt wer- den, worauf dem Gemisch 10 y6 Wasser zugegeben wird und äme Gemisch unter einem Druck von etwa Zoo atü verdichtet und in einem Autoklaven einem Druck von etwa 16 atü und einer Temperatur von etwa 2ooo 0 ausgesetzt wird. Nach diesem Verfahren hergestellte Haukörper weisen Festigkeitswerte von etwa 9oo Kg%em2 auf. A process for preparing betonartigem material of high geetigkeit The invention relates to a process for the preparation of betonartigem high strength material in which dos according to the teaching main patent about? 0% fat clay and 30% lime is ground finely and in a dry state intimately mixed advertising to, whereupon the mixture 10 y6 water is added and compacted atm dme mixture under a pressure of about zoo and a pressure of about 16 atm and a temperature of about 0 2ooo is exposed in an autoclave. Housings produced according to this process have strength values of about 900 kg% em2 .

Gemäss der Erfindung können Baukörper dieser Art in zwei- . facher Beziehung verbessert werden.According to the invention, structures of this type can be divided into two . multiple relationship can be improved .

Eine Erhöhung der mechanischen Festigkeit bis zu Werten über 1 5oo Kgjcm2 wird dadurch erreicht, dann das Gemisch nach der Behandlung im itutoklaven mehrere Stunden einer weiteren Wärmebehandlung in einem Trockenofen bei einer Temperatur von etwa 4ooo C unterworfen wird. An increase in the mechanical strength up to values over 1 5oo Kgjcm2 is achieved, then the mixture is subjected to after treatment in itutoklaven several hours a further heat treatment in a drying oven at a temperature of about 4ooo C.

Besteht die Gefahr, dass Baukörper dieser Art aufgrund der Wärmebehandlung $u Risabildungen neigene was eine Folge eines zu hohen Ton-Gehaltee des fetten Uhses sein kann, so kann diese Gefahr dadurch beseitigt werden, amen dem Gemisch vor seiner Verdichtung sehr feiner Quarzsande vorzugsweise in einer Menge von 1o bis 2o 96, beigegeben wird. There is a risk that building of this type due to the heat treatment $ u Risabildungen neigene which may be a consequence of a high clay Gehaltee Fat Uhses, this risk can be eliminated by, verily the mixture prior to its compression very fine quartz sand, preferably in a Quantity from 1o to 2o 96 is added.

Diese verhältnismäasig einfachen Modifikationen des Verfahrens nach dem Hauptpatent führen somit zu sehr wesentlichen Verbesserungen der nach der hehre den Hauptpatentes herge- stellten Haukörper. Im falle der zusätzlichen Wärmebehandlung ist die Verbesserung vermutlich darauf zurückzuführen, dass die während der ersten Wärmebehandlung gebildeten Kalzium#.-eilikate im Verlaufe der zusätzlichen Wärmebehandlung in Kalziumsilikate mit einem niedrigeren Wassergehalt und grUeserer Härte umgewandelt werden.This verhältnismäasig simple modifications of the method according to the main patent thus lead to very significant improvements introduced by the lofty main patent manufactured Haukörper. In the case of the additional heat treatment , the improvement is probably due to the fact that the calcium silicates formed during the first heat treatment are converted into calcium silicates with a lower water content and greater hardness in the course of the additional heat treatment.
