Abstract
This geopolymer molding production method comprises: a mixing step (S1) for mixing a first material containing aluminum and silicon with a hydrate of an alkali stimulant containing a hydrate of an alkaline hydroxide and/or a hydrate of an alkaline silicate; a compaction step (S2) for compacting the mixture obtained in the mixing step (S1) into a compacted mixture; and a curing step (S3) for curing the compacted mixture.
Claims15
A geopolymer molding production method comprising:
- a mixing step in which a first substance containing aluminum and silicon is mixed with hydrate of an alkaline stimulant containing at least one of alkaline hydroxide hydrate and alkaline silicate hydrate;
- a compression step in which a compressed mixture is formed by performing compression molding on a mixture obtained in the mixing step;
- and
- a curing step in which the compressed mixture is cured.
A geopolymer molding production method comprising:
- a mixing step in which a first substance containing aluminum and silicon, an alkaline stimulant containing at least one of alkaline hydroxide and alkali silicate, and hydrate containing crystal water are mixed;
- a compression step in which a compressed mixture is formed by performing compression molding on a mixture obtained in the mixing step;
- and
- a curing step in which the compressed mixture is cured.
A geopolymer molding production system comprising:
- a mixture preparator configured to prepare a mixture by using at least a first substance containing aluminum and silicon and a second substance containing at least one of alkaline hydroxide and alkaline silicate from the first substance, the second substance, and a third substance which contains a compound having hydrate, in such a manner that the mixture contains aluminum and silicon as a first condition, the mixture contains at least one of alkaline hydroxide and alkaline silicate as a second condition, the mixture contains a compound having hydrate as a third condition;
- a pressurizer equipped with a mold for containing the mixture and configured to apply pressure having been set in the mold;
- and
- a curing unit configured to maintain the mixture compression-molded by the pressurizer and equipped with an air conditioner adjusting temperature of atmosphere around the mixture.
