Title (EN) PLASTICIZER-CONTAINING HARDENING ACCELERATOR COMPOSITION
(FR) COMPOSITION D'UN ACCÉLÉRATEUR DE DURCISSEMENT CONTENANT UN PLASTIFIANT
Abstract: front page image
(EN)The invention concerns a process for the preparation of a hardening accelerator composition by reaction of a water-soluble calcium compound with a water-soluble silicate compound and a process for the preparation of a hardening accelerator composition by reaction of a calcium compound with a silicon dioxide containing component under alkaline conditions, in both cases the reaction of the water-soluble calcium compound with the water-soluble silicate compound being carried out in the presence of an aqueous solution which contains a water-soluble comb polymer suitable as a plasticizer for hydraulic binders. The invention concerns also a composition of calcium silicate hydrate and comb polymer, its use as hardening accelerator and for the reduction of the permeability of hardened compositions.
(FR)L'invention concerne un procédé de préparation d'une composition d'un accélérateur de durcissement, par réaction d'un composé de calcium hydrosoluble avec un composé de silicate hydrosoluble, ainsi qu'un procédé de préparation d'une composition d'accélérateur de durcissement, par réaction d'un composé de calcium avec un composant contenant du dioxyde de silicium, dans des conditions alcalines, la réaction du composé de calcium hydrosoluble avec le composé de silicate hydrosoluble étant effectuée, dans les deux cas, en présence d'une solution aqueuse qui contient un polymère peigne hydrosoluble approprié comme plastifiant pour liants hydrauliques. L'invention concerne également une composition de silicate de calcium hydraté et de polymère peigne, son utilisation comme accélérateur de durcissement et pour la réduction de la perméabilité de compositions durcies.
