L’ajout d’adjuvants dans les mortiers permet d’obtenir diverses propriétés selon lesperformances souhaitées. Les polysaccharides sont utilisés pour améliorer la capacité derétention d’eau et le comportement rhéologique du mortier. Cependant, ils engendrent unretard de prise du ciment et représentent un poids économique considérable. Il apparaît doncque la compréhension de l’interaction entre les polysaccharides et le ciment est nécessaire.Etant donné que les comportements sont différents selon le type de polysaccharide, l’étuded’une nouvelle famille de polysaccharides constitue un axe de recherche majeur. Leshydroxypropylguars (HPG) ont été choisis car ils ont été présentés comme de très bonsagents rétenteurs d’eau et sont déjà utilisés ind...
