Abstract:
The present invention provides a method for producing a cured article of a hydraulic composition, prepared by mixing glycerol, cement and water, the hydraulic composition containing a sulfate ion, the method including step 1 of preparing the hydraulic composition such that a molar ratio of the sulfate ion to the glycerol, sulfate ion/glycerol, is 5.0 to 20 and the content of the sulfate ion is 3.0 to 15 parts by weight to 100 parts by weight of cement; and step 2 of aging and curing the hydraulic composition obtained in the step 1.
