摘要： PROBLEM TO BE SOLVED: To prevent a setting retarder included in an admixture for cement which controls the heat of hydration of cement and releases the setting retarder included therein when the temperature is above the prescribed temperature from being released due to breakage of the admixture for cement when the admixture for cement is kneaded with the cement, aggregate, etc., by enhancing the dynamic strength of the above admixture for cement. SOLUTION: The dynamic strength of the admixture for cement is enhanced and the admixture for cement is made hardly breakable in kneading the same with the cement, the aggregate, etc., by manufacturing the setting retarder of powder by mixing the same in the state of solid into an organic material in such a manner that the organic layer is formed in tight contact with the surroundings of the setting retarder of the solid.
