<P>PROBLEM TO BE SOLVED: To solve the problem wherein, in production of a geopolymer cured body obtained by reacting alminosilicate with an alkali solution, when using an inexpensive sodium compound, industrial execution is difficult because of a short setting start time. <P>SOLUTION: A treatment is applied, in which a geopolymer precursor obtained by mixing alminosilicate with an alkali solution is heated beforehand at a prescribed temperature or higher and held for a prescribed time, to be thereby able to delay the setting start time greatly, and to secure a sufficient usable life. Hereby, industrial level production of the geopolymer cured body using an inexpensive sodium compound as the alkali solution becomes possible. <P>COPYRIGHT: (C)2013,JPO&INPIT |
