Influence of Polysaccharides on Cement Hydration
The influence of polysaccharides on cement hydration was studied. Three polysaccharides were studied: a cellulose ether (CE), a starch ether (SE) and a dextrin (YD). In a concentrated dilute medium, admixture CE only revealed a slight effect on cement hydration. Portlandite and ettringite formation...

| Zusammenfassung: | The influence of polysaccharides on cement hydration was studied. Three polysaccharides were studied: a cellulose ether (CE), a starch ether (SE) and a dextrin (YD). In a concentrated dilute medium, admixture CE only revealed a slight effect on cement hydration. Portlandite and ettringite formation and gypsum consumption were slowed down by SE adjunction. Admixture YD induced an acceleration of ettringite formation and gypsum consumption whereas portlandite formation was blocked by this compound. 10 refs. |
