POLYSACCHARIDE DERIVATIVES HAVING AN ADJUSTED PARTICLE MORPHOLOGY FOR HYDROLYTICALLY SETTING COMPOSITIONS

摘要

PURPOSE: A manufacturing method of hydrolysable setting composition is provided to simply add a set micro polysaccharide compound to a hydrolysable setting composition, thereby obtaining improved lump rating and/or moisture retainability. CONSTITUTION: A manufacturing method of hydrolysable setting composition comprises a step of adding micro polysaccharide compound having intermediate particle diameter DOP (50,3) of at least 38 micron, and intermediate article diameter EQPC (50,3) of equivalent particle circle of at least 80 micron into a hydrolysable setting composition. The hydrolysable setting compostion does not contain a micro polysaccharide compound before adding the micro polysaccharide compound.
