PRODUCTION METHOD OF CEMENT BASED HYDRATION MIXTURE, CEMENT BASED HYDRATION MIXTURE, AND CEMENT BASED CURED BODY

PROBLEM TO BE SOLVED: To provide a production method of a cement based hydration mixture that can prevent a crack generated by dry shrinkage or autogenous shrinkage that arises from that a concrete and a mortar that are a representative of a cement based water cured body are installed and then exposed to a natural environment, and further that has self-repairing of a crack after the crack; the cement based hydration mixture; and a cement based cured body.SOLUTION: A production method of a cement based hydration mixture is characterized in that a polysaccharide that is collected from a cultivation body in which a pseudomonas bacterium is cultivated, and that a viscosity rises in a high alkali condition which a cement mixture forms to become a gel state is mixed when milling and mixing a cement.
