Abstract
(DE)
Ethylenoxid/Propylenoxid-Blockcopolymere mit einem Gehalt an 5 bis 35 Gew.-% Ethylenoxygruppen und Molmassen des Polypropylenglykolblocks im Bereich von 1500 bis 3000 führen beim Zusatz zu trockenen, hydraulisch abbindenden Massen zu einer Verminderung des Staubens, zu einer Verbesserung der Benetzbarkeit sowie zu einer Verbesserung des Fließverhaltens der mit Wasser versetzten Massen.
(EN)
The addition of ethylene oxide/propylene oxide block copolymers containing 5 to 35 wt. % of ethylene oxy groups and molar masses of the polypropylene glycol block between 1500 and 3000 to dry, hydraulic binder materials results in reduced dust formation, improved wettability and enhanced flow properties of these materials when they are mixed with water.
(FR)
L'adjonction de copolymères en masse d'oxyde d'éthylène/oxyde de propylène, renfermant 5 à 35 % en poids de groupes d'éthylèneoxy et des masses molaires du bloc de polypropylèneglycol dans la plage de 1500 à 3000, à des matières sèches à prise hydraulique a pour effet de réduire la formation de poussière, d'améliorer la mouillabilité ainsi que la visco-élasticité de ces matières mélangées avec de l'eau.
