Title
(EN) CEMENT ACCELERATING ADMIXTURE
(FR) ADDITIF ACCELERATEUR POUR CIMENT
Abstract
(EN)
An accelerating admixture for use with sprayable cementitious compositions such as shotcrete comprises a mixture of (a) amorphous aluminium hydroxide and/or aluminium hydroxysulphate, and (b) at least one amine, preferably an alkanolamine. In a preferred embodiment, the admixture also comprises an aqueous dispersion of at least one polymer which comprises pendant carboxylic moieties.
(FR)
Un additif accélérateur destiné à être utilisé avec des compositions du type ciment pouvant être appliquées par pulvérisation, tel que du béton projeté, comprend un mélange (a) d'hydroxyde d'aluminium amorphe et/ou d'hydroxysulphate d'aluminium, et (b) d'au moins une amine, de préférence une alcanolamine. Dans un mode réalisation préféré, l'additif présenté comprend également une dispersion aqueuse d'au moins un polymère, contenant des fractions carboxyliques.
