Abstract

Studies have been carried out to investigate the concrete corrosion inhibitor performance of silica fume admixture and an admixture of amino alcohols containing organic and inorganic substances. The concrete specimens with and without admixtures were subjected to accelerated corrosion tests to determine the time to corrosion initiation. The results showed that the specimens admixtured with nitrogen containing organic and inorganic inhibitors performed slightly better than concrete specimens with silica fume admixture.

Kurzfassung

Für den vorliegenden Beitrag wurden Studien durchgeführt, um die Performanz von Mikrosilica-Zusätzen und von anorganisch-organisch gemischten Zusätzen mit Aminoalkoholen bezüglich des Korrosionsverhaltens von Beton zu untersuchen. Die Betonproben mit und ohne diese Zusätze wurden einem beschleunigten Korrosionstest unterworfen, in dem die Zeit zur Initiierung der Korrosion bestimmt wurde. Die Ergebnisse zeigten, dass sich die Proben mit stickstoffhaltigen organischen und anorganischen Zusätzen etwas besser verhielten als die Proben mit einem Zusatz aus Mikrosilica.
