PROBLEM TO BE SOLVED: To provide a kneading method for a cement-based mixture which enables the characteristics feature of the cement-based mixture where a thickening admixture made by combining two kinds of a water-soluble low-molecular compound and a water reducing admixture are blended to be maintained as it is, and the property of a primary kneaded mixture by adding only one side water soluble low molecular compound to be left kneaded and pressure-fed by a pump. SOLUTION: When the cement-based mixture is manufactured, the primary kneaded mixture is manufactured by kneading the cement and an aggregate, primary kneading water, and a second water-soluble low-molecular compound (B) selected from an anionic aromatic compound, a first water-soluble low-molecular compound (A) selected from cationic surfactants, a later additive such as a water reducing admixture or the like and secondary kneading water are charged to the primary kneaded mixture, and kneaded again to prepare the cement-based mixture.
