<p>PROBLEM TO BE SOLVED: To provide a geopolymer cured product unlikely to entail, even if a boron ore is included therein, strength attenuations and suitable for long-term uses.SOLUTION: A geopolymer including an aluminosilicate oxide as a main component is mixed with a boron ore. The curing of the geopolymer progresses as a result of the polymerization of a metal eluted from a filler with a silicic acid complex of a geopolymer liquid. The geopolymer is impervious to curing hindrances attributed to the elution of BOfrom the boron ore. The strength of the geopolymer cured product therefore manifests even if a finely granulated boron ore is dispersed therein without entailing the hindrance of the curing thereof. Moreover, it is desirable to use boron ore particles having diameters of 20 mm or less since they can be homogeneously dispersed. Moreover, it is desirable, from the standpoint of facilitating the manifestation of superior strength, to heat and cure, after a yet-to-be-solidified geopolymer has been filled into a frame mold, the filled geopolymer at 40°C or above and 100°C or below.</p> |
