EFFLORESCENCE INHIBITOR FOR CEMENT COMPOSITION
PROBLEM TO BE SOLVED: To provide an efflorescence prevention agent for a cement composition excellent in efflorescence prevention property.SOLUTION: The efflorescence inhibitor for a cement composition is provided that contains a polyoxyalkylene compound (X) represented by formula (1); R-N{(-AO)n-H}or the efflorescence inhibitor for a cement composition is provided that is composed of a polyoxyalkylene compound (X) represented by the formula (1) and at least one porous powder (Y) selected from the group consisting of silicon oxide, aluminum oxide, calcium carbonate and magnesium carbonate. In formula (1), Rrepresents any one of an alkyl group, an alkenyl group, a cycloalkyl group and an aryl group; AO represents an oxyalkylene group having 2 to 4 carbon atoms; N represents a nitrogen atom; H represents a hydrogen atom; and n represents an integer of 2 to 15.SELECTED DRAWING: None
