Abstract

The present invention relates to polysaccharide derivatives having an adjusted particle morphology for use in the preparation of a hydraulic setting composition having an adjusted lump rating. The invention further relates to a method of adjusting the lump rating of a hydraulic setting composition comprising adjusting the particle morphology of a particulate polysaccharide derivative. Furthermore, the invention is directed to a hydraulic setting composition comprising a particulate polysaccharide derivative having an adjusted particle morphology. The invention is also directed to various uses of the particulate polysaccharide derivative having an adjusted particle morphology.
