Abstract

The invention relates to a process for improving the physical properties of cement pastes, cement mortars and concrete by the addition of terpene polymers, in particular of liquid low-molecular terpenes alone or as a mixture with other terpene hydrocarbons, which are added to the cement-containing building materials in a quantity of 0.1-10 % by weight, relative to the binder weight, whereby an increase in strength by 20-30 %, a reduction in efflorescence and a reduction in water absorption are obtained.

Description

Die Erfindung betrifft ein Verfahren zur Ver- The invention relates to a method for

besserung der physikalischen Eigenschaften von Zementleimen, Zementmörteln, Beton und dergleichen.improvement of the physical properties of cement glues, cement mortars, Concrete and the like.

Die Verwendung von Terpenen bzw. Terpenpolymeren oder Isoprenoiden ist weitverbreitet. So werden diese Verbindungen bei der Herstellung von Klebstoffen, bei der Textilausrüqtungzur Kaschierung von Papieren, bei der Herstellung von Anstrichmitteln, sowie in der kosmetischen Industrie und dergleichen eingesetzt. Auch als Ausgangsstoffe für die Synthese von Vitaminen und Pharmazeutika, sowie in der Gewürz-, Aromen- und Essenzenindustrie werden Terpene oder Terpenverbindungen verwendet. The use of terpenes or terpene polymers or isoprenoids is widespread. This is how these connections are used in the manufacture of adhesives, in textile finishing for lamination of papers, in the production of paints, as well as used in the cosmetic industry and the like. Also as starting materials for the synthesis of vitamins and pharmaceuticals, as well as in the spice, aroma and the essence industry, terpenes or terpene compounds are used.

Es wurde nun gefunden, daß derartige polymere Terpene die physikalischen Eigenschaften von Zementleimen, Mörteln und Beton wesentlich verbessern können. Die genaue Ursache der Verbesserung der physikalischen Eigenschaften konnte bisher nicht eindeutig geklärt werden, jedoch tritt bei Zusatz solcher Polymere eine Festigkeitssteigerung ein, die erheblich über derjenigen bekannter Zusätze bei zementhaltigen Baustoffen liegt. It has now been found that such polymeric terpenes are the physical Can significantly improve the properties of cement glues, mortars and concrete. The exact cause of the improvement in physical properties could be so far cannot be clearly clarified, but the addition of such polymers results in an increase in strength one that is considerably higher than that of known additives for cementitious building materials lies.

Die Erfindung wird anhand eines Beispiels beschrieben: Bei einem Zusatz von Terpenen, beispielsweise von 0,5 Gew.-% eines Isoprenoids mit 20 C-Atomen, bezogen auf das Zementgewicht, trat eine Festigkeitssteigerung von ca 20-30 %1 eine Verringerung der Effloreszens und eine Verringerung der Wasseraufnahme ein. Die Effloreszenzverminderung konnte auch durch Aufsprühen von flüssigen oder gelösten Terpenen erreicht werden. The invention is described using an example: In a Addition of terpenes, for example 0.5% by weight of an isoprenoid with 20 carbon atoms, Based on the cement weight, there was an increase in strength of approx. 20-30% 1 Reduction in the efflorescence and a decrease in water intake. the Efflorescence reduction could also be achieved by spraying liquid or dissolved Terpenes can be achieved.
