Admixtures for mineral binders, based on sugar (oxide) and of sugar, 1996, the mineral binders and their method of preparation of adjuvant

摘要

The invention is to provide a novel admixture for mineral binders consisting of a composition containing a sugar or an oxidised sugar and a sugar hydrogéné.le oxidised sugar may consist, in particular of gluconic acid or one of its salts or in a starch hydrolysate oxydé.le hydrogenated sugar may consist, in particular of the maltitol, sorbitol, mannitol, xylitol, of the arabitol, or a hydrogenated starch hydrolysate containing at least 40% by weight of maltitol.au the adjuvant, this composition may be associated with the usual adjuvants such as phosphates, borates or amines.l' combination of a sugar or an oxidised sugar and hydrogenated sugar within this composition makes it possible to obtain synergistic effects, in particular in terms of plasticity and mechanical properties of the binders minéraux.les adjuvants claimed can be used both for the review of the cements, the raw materials for cements, as for the review of the mortars and concretes slurry.
