    摘要: The present invention relates to a segregation reducing agent consisting of curdlan and alkaline materials and a hydraulic composition containing the segragation reducing agent, particularly, the present invention relates to the segregation reducing agent prepared by alkalifying a curdlan-producing fermentation broth per se or a curdlan powder with an alkaline material, and also relates to hydraulic compositions, concrete and mortar, comprising the segregation educing agent. This segregation reducing agent can provide a great segregation reduction effect for hydraulic compositions even at its small amount as well as guarantee the strength, filling ability and fluidity.
