Title (EN) METHOD FOR ACCELERATING THE SETTING AND HARDENING OF HYDRAULIC BINDING AGENTS AND MIXTURES CONTAINING THE SAME
(FR) PROCEDE POUR ACCELERER LA PRISE ET LE DURCISSEMENT DE LIANTS HYDRAULIQUES ET DE MELANGES CONTENANT CES DERNIERS
(DE) VERFAHREN ZUR BESCHLEUNIGUNG DES ABBINDENS UND ERHÄRTENS VON HYDRAULISCHEN BINDEMITTELN UND DIESE ENTHALTENDEN GEMISCHEN
Abstract:
(EN) The invention relates to an accelerator used for setting and hardening and a method for accelerating and hardening hydraulic binding agents using said accelerator. The principal components of said accelerator are nitrates, aminoalcohols, hydroxycarboxylic acids and polyalcohols. The hardening acceleration is not connected with a rapid loss in processability, which is common in other accelerated systems.
(FR) L'invention concerne un accélérateur de prise et de durcissement ainsi qu'un procédé pour accélérer la prise et le durcissement de liants hydrauliques au moyen d'un tel accélérateur. Les constituants de cet accélérateur qui sont essentiels pour l'accélération sont le nitrate, l'alcanolamine, l'acide hydroxycarboxylique et le polyol. L'accélération du durcissement ne s'accompagne pas d'une perte rapide d'aptitude à la mise en oeuvre, à la différence des systèmes accélérés connus.
(DE) Beschrieben werden ein Abbinde- und Erhärtungsbeschleuniger und ein Verfahren zur Beschleunigung des Abbindens und Erhärtens von hydraulischen Bindemitteln unter Zugabe eines solchen Beschleunigers. Die für die Beschleunigung wesentlichen Bestandteile dieses Beschleunigers sind Nitrat, Alkanolamin, Hydroxycarbonsäure und Polyol. Die Erhärtungsbeschleunigung ist nicht mit einem raschen Verlust an Verarbeitbarkeit verbunden, welche sonst bei beschleunigten Systemen üblich ist.
