<P>PROBLEM TO BE SOLVED: To provide a method for improving strength of a cured article of a hydraulic composition without applying curing, for example, heating to a hydraulic composition after being prepared. <P>SOLUTION: In the method for producing a cured article of a hydraulic composition prepared by mixing a compound containing alkali metal ion, glycerol, cement and water, the hydraulic composition contains sulfate ion. The method for producing the cured article of the hydraulic composition includes step 1 of preparing the hydraulic composition such that a molar ratio of the sulfate ion to the glycerol, sulfate ion/glycerol, is 3.2 to 25 and the content of the alkali metal ion is 0.05-1.0 part by weight to 100 parts by weight of cement; and step 2 of aging and curing the hydraulic composition obtained in the step 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
