Admixtures for mineral binders based on (oxidised) sugar and hydrogenated sugar, admixture-containing mineral binders, and a process for the preparation thereof

摘要: The invention relates to a novel admixture for mineral binders, composed of composition containing at the same time sugar or an oxidized and hydrogenated sugar. may consist, in particular, gluconic acid one its salts starch hydrolysate. consist particular maltitol, sorbitol, mannitol, xylitol, arabitol, hydrolysate least 40% by weight maltitol. Within admixture, this be combined with conventional admixtures such as phosphates, borates, amines. combination within makes it possible obtain synergistic effects, particularly terms plasticity mechanical properties binders. claimed used equally well admixing cements, raw materials cements mortars, slurries concretes. They also other sectors as, example, plaster industry, complexing agents hydration dehydration controllers.
