SETTING RETARDER FOR INORGANIC MOLDING SURFACE AND METHOD FOR MANUFACTURING INORGANIC MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a setting retarder for an inorganic molding surface such as a concrete or the like capable of washing out in an arbitrary period such as, for example, by an operator who is free from an operation even after an accelerated curing and forming a uniform washing-out surface not having an unevenness. SOLUTION: The setting retarder for the inorganic molding surface comprises a vinyl alcohol polymer containing a silanol group in a molecule.
