Title (EN) USE OF POLYCONDENSED AMINOSILANES IN A HYDRAULIC COMPOSITION FOR IMPROVED CARBONATION RESISTANCE
(FR) UTILISATION D'AMINOSILANES POLYCONDENSES DANS UNE COMPOSITION HYDRAULIQUE POUR UNE RESISTANCE A LA CARBONATATION AMELIOREE
Abstract: front page image
(EN)The present invention relates to the use of at least one polycondensed aminosilane having a molecular weight of between 600 g/mol and 1,000,000 g/mol. Said polycondensed aminosilane is combined with at least one hydraulic binder in a hydraulic composition so as to reduce and/or prevent carbonation in said hydraulic composition. Said polycondensed aminosilane(s) is/are present in the hydraulic composition in a weight ratio of polycondensed aminosilane(s)/binder of between 0.05% and 5.0%.
(FR)La présente invention concerne l'utilisation d'au moins une aminosilane polycondensée, ayant un poids moléculaire compris de 600 g/mol à 1000000 g/mol,en association avec au moins un liant hydraulique dans une composition hydraulique, pour réduire et/ou prévenir la carbonatation au sein de ladite composition hydraulique, ladite ou lesdites aminosilane (s) polycondensée(s)étant présente(s)dans la composition hydraulique selon un rapport pondéral aminosilane(s) polycondensée(s)/liant compris de 0,05 %à 5,0 %.
