<p>A storing and/or transferring method of an alkoxy(poly)alkylene glycol-containing material for cement additive polymer which comprises a step of filling a vessel, a step of storing and/or transferring and a step of drawing out, in that order, said alkoxy(poly)alkylene glycol being represented by the following general formula (1) ; R<1>O(R<2>O)nH in the formula, R<1> represents a hydrocarbon group containing 1 to 30 carbon atoms, R<2>O group represents an oxyalkylene group containing 2 to 18 carbon atoms and each R<2>O group may be the same or different and n represents the average number of moles of the oxyalkylene groups represented by R<2>O as added and is a number of 0 to 300, and said step of storage and/or transfer being carried out at a temperature not higher than the solidifying point of the material for cement additive polymer.</p> |
