摘要：
In the invention, a hydraulic powder is prepared by a step of grinding a hydraulic compound in the presence of compound (a) that is obtained by adding an alkyleneoxide having 2 to 4 carbon atoms to a compound which has no amino group, but has an active hydrogen, provided that polyethyleneglycol and polypropyleneglycol are excluded. Alternatively, the hydraulic compound can be ground in the presence of compound (a) and anti-foaming agent (b).
