Shrinkage-reducing agent for hydraulic material and shrinkage-reducing agent composition for hydraulic material
Provided are a shrinkage-reducing agent for a hydraulic material and a shrinkage-reducing agent composition for a hydraulic material including a compound represented by the general formula (1): R1—[O-(A1O)m—R2]n (1), where: R1 represents R1 derived from a polyhydric alcohol represented by R1—[OH]n; A1O represents an oxyalkylene group having 2 to 18 carbon atoms; R2 represents a hydrogen atom or a hydrocarbon group having 1 to 30 carbon atoms; m represents an average added mole number of oxyalkylene groups A1O's; n represents 3 or 4; and when n equals 3, m represents 30 to 150, and when n equals 4, m represents 5 to 150.
