PROBLEM TO BE SOLVED: To provide the problem that, in the production of a geopolymer cured body obtained by reacting aluminosilicate and an alkali solution, when an inexpensive sodium compound is used, since condensation starting time is short, industrial enforcement is difficult.SOLUTION: A geopolymer precursor obtained by mixing aluminosilicate and an alkali solution is previously warmed to a prescribed temperature or more and is also subjected to treatment of being held for a prescribed time, thus solidification starting time is remarkably delayed, and the securing of sufficient working life is made possible. In this way, the production on an industrial level of a geopolymer cured body using an inexpensive sodium compound as an alkali solution is made possible. |
