Description

Verfahren zur Herstellung von porösen Baumaterialien aus hydraulischen Bindemitteln Durch das, Hauptpatent ist ein Verfahren zur Herstellung von porösen Baumaterialien geschützt, wonach man hydraulische Bindemittel, gegebenenfalls zusammen mit Zuschlagstoffen, mit bestimmten Sulfosä Uren bzw. deren Salzen und der Anmachflüssigkeit zu einem Schaum verarbeitet und. diesen dann in-an sich bekannter Weise vergießt.Process for the production of porous building materials from hydraulic By the, main patent is a process for the production of porous binders Building materials are protected, after which hydraulic binders are put together, if necessary with aggregates, with certain sulphonic acids or their salts and the mixing liquid processed into a foam and. this then sheds in a manner known per se.

Es wurde nun gefunden, daß die Porosität der Masse und die Stabilität des Schaumes beträchtlich gesteigert wird, wenn man der Masse vor dem Abbinden gelöste Alkalisilikate, z. B. Wasserglas, zusetzt.It has now been found that the porosity of the mass and the stability of the foam is increased considerably if the mass is dissolved before it has set Alkali silicates, e.g. B. water glass, adds.

Beispiel. 6 i, 2 5 kg Sand von o bis 3 mm Körnung werden mit 17,5 kg Portlandzement, 175g isopropylsulfosaurcm Natrium sowie 12,61 Wasser in einem Betonmischer kurze Zeit gemischt, darauf in dünnem Strahl und unter Verteilung über die ganze Masse 6qoccm Natronwasserglas von. 35° B6 zugegeben und kurze Zeit weitergemischt. Die abgebundene trockene Masse hat ein Raumgewicht von 1,26.Example. 6 i, 2 5 kg of sand with a grain size of 0 to 3 mm are 17.5 kg Portland cement, 175g isopropylsulfosaurcm sodium and 12.61 water in one Cement mixer mixed for a short time, then in a thin stream and under distribution over the whole mass 6qoccm soda water glass of. 35 ° B6 was added and mixing continued for a short time. The set dry mass has a density of 1.26.
