Description

Herstellung von Mörtelmischungen Stellt man Bauplatten oder sonstige geformte Bauelemente- aus anorganischen Bindemitteln, z. B. Zement oder Gips, einerseits und anorganischen oder organischen Füll- und Faserstoffen, wie Holzwolle, Sägemehl, Steinmehl, Bimssand, andererseits sowie Wasser her, so erhält man Fertigerzeugnisse, deren Festigkeit oft nicht besonders hoch ist. Zur Verbesserung der Festigkeit werden nach älteren und neueren Vorschlägen während des Mischens der Grundbestandteile in kleinem Ausmaße verschiedenartige Zusatzstoffe zugesetzt, vor allem solche wasserlöslicher Art, wie Sulfate, Chloride, Nitrate, ferner organische Säuren oder deren Salze u. dgl. In der Regel fügt man diese Zusatzstoffe während des Mischens der festen Grundbestandteile als trockenes Pulver zu.Production of mortar mixes If building boards or other are provided shaped components made of inorganic binders, e.g. B. cement or plaster of paris, on the one hand and inorganic or organic fillers and fibers, such as wood wool, sawdust, Stone flour, pumice sand, on the other hand, as well as water, this is how you get finished products, whose strength is often not particularly high. To be used to improve strength according to older and newer suggestions while mixing the basic ingredients Various additives are added on a small scale, especially those that are water-soluble Kind, such as sulfates, chlorides, nitrates, also organic acids or their salts and. Like. As a rule, these additives are added while the solid basic ingredients are being mixed as a dry powder too.

Es hat sich nun gezeigt, daß man die bei diesen Verfahren erzielten Festigkeitswerte, insbesondere auch die Biegefestigkeitswerte, noch erheblich steigern kann, wenn man die obengenannten Zusatzmittel vor ihrer Zugabe zu den übrigen Bestandteilen der Formmassen einer möglichst innigen Mischung mit gewissen unlöslichen pulverförmigen Ballaststoffen unterwirft, die an sich nicht verfestigend wirken. Bei diesen Stoffen kann es sich' um anorganische Stoffe, wie z. B. Kalkstein-, Basalt- oder Schiefermehl, Talkum usw., oder um organische Stoffe, wie Weichholzmehl, Rindenmehl usw., handeln. Es können gelegentlich auch mit besonderem Vorteil Gemische von organischen und anorganischen Stoffen Verwendung finden. Auf die innige Vorvermischung kommt es dabei besonders an, denn wie die nachstehende Tabelle zeigt, ist die Festigkeitsverbesserung nicht zu erzielen, wenn man etwa wasserlösliche "Zusatzmittel und die erwähnten Ballaststoffe getrennt zugibt.

These substances can be 'inorganic substances, such as. B. limestone, basalt or slate flour, talc, etc., or organic substances such as softwood flour, bark flour, etc. act. Occasionally, mixtures of organic and inorganic substances can also be used with particular advantage. Intensive premixing is particularly important because, as the table below shows, the improvement in strength cannot be achieved if, for example, water-soluble additives and the aforementioned dietary fibers are added separately.
