Abstract
A segregation reducing agent for a hydraulic composition which is obtained by adding a water-soluble thickener to a culture of a microorganism capable of producing a .beta.-1,3-glucan selected from the group consisting of curdlan, palamylon and pachyman, in a sufficient amount to give a viscosity to the culture of from about 200 to 2000 cp, followed by spray drying so as to form a powder having a core of the .beta.-1,3-glucan and a coating of the water-soluble thickener.
