Title
(EN) IMPROVED VERY HIGH EARLY STRENGTH CEMENT
(FR) CIMENT AMELIORE A PRISE RAPIDE A RESISTANCE ELEVEE
Abstract
(EN)
A combination of a hydroxy polycarboxylic acid and sucrose improves the water-demand, setting, and compressive strength properties of a calcium sulfoaluminate cement to a greater degree than would be the case if the hypothetical cumulative effect of two admixtures were operative.
(FR)
La combinaison d'un acide hydroxy polycarboxylique et de sucrose ameliore la demande en eau, la prise, et les proprietes de resistance a la compression d'un ciment de sulfoaluminate de calcium dans une mesure plus grande que cela ne se produirait si l'effet cummulatif theorique des deux melanges s'exercait.
