Description
Verfahren zur Verbesserung der Eigenschaften von Zementmörtel oder Beton Das Verfahren zur Verbesserung der Eigenschaften von Zementmörtel oder Beton nach dem Patent 1065 313 besteht darin, daß vor oder bei der Verarbeitung des Zements geringe Mengen phenolischer Verbindungen zugesetzt werden. Als phenolische Verbindungen werden gemäß diesem Patent Phenol, Kresole oder Naphthole, vorzugsweise in alkalischer Lösung, ferner vorzugsweise in Verbindung mit bekannten plastifizierenden bzw. luftporenbildenden Zusatzmitteln verwendet.Method for improving the properties of cement mortar or concrete The method for improving the properties of cement mortar or concrete according to patent 1065 313 consists in adding small amounts of phenolic compounds before or during the processing of the cement. According to this patent, the phenolic compounds used are phenol, cresols or naphthols, preferably in alkaline solution, further preferably in conjunction with known plasticizing or air-entraining additives.
Durch diese Zusätze werden wesentlich erhöhte Endfestigkeiten erzielt, wobei der Abbindeprozeß in der Regel merklich beschleunigt, zumindest aber nicht verzögert und die Lufteinführung verringert wird.With these additives, significantly increased final strengths are achieved, whereby the setting process is noticeably accelerated as a rule, but at least not delayed and the air intake is reduced.
Ähnliche Wirkungen erzielt man auch, wenn man als Zusätze statt der genannten Phenole deren Substitutionsprodukte verwendet, welche im Kern statt Wasserstoff mehr oder weniger Halogen-, Nitro- oder Aminogruppen enthalten. Diese Substitutionsprodukte sind also zur Verbesserung der Eigenschaften von Zementmörtel oder Beton mit einem technischen Effekt etwa gleicher Größenordnung wie die nichtsubstituierten Phenole verwendbar.Similar effects can also be achieved when using additives instead of named phenols whose substitution products are used, which in the core instead of hydrogen contain more or less halogen, nitro or amino groups. These substitution products So are to improve the properties of cement mortar or concrete with one technical effect about the same order of magnitude as the unsubstituted phenols usable.
