FIELD: chemistry; technological processes.
SUBSTANCE: group of inventions relates to a method of producing a moulded article from a geopolymer and a system for producing a moulded article from a geopolymer. Method of producing a moulded article from a geopolymer involves a mixing step, a pressing step and a curing step, on which the compacted mixture is cured. At the mixing stage, the first substance containing aluminium and silicon is mixed with alkali stimulator hydrate, which includes an alkali metal silicate hydrate. At the pressing step, the moulded mixture is obtained by direct pressing of the mixture obtained at the mixing step. Hydrate of the alkaline stimulator contains at least one hydrate of lithium silicate, sodium silicate hydrate, hydrate of potassium silicate, hydrate of caesium silicate and hydrate of rubidium silicate. According to the second embodiment, the alkaline stimulator hydrate contains at least one of lithium aluminate hydrate, sodium aluminate hydrate, potassium aluminate hydrate, rubidium aluminate hydrate and caesium aluminate hydrate. According to the third embodiment, at the mixing stage, the first substance containing aluminium and silicon is mixed, an alkaline stimulator containing at least one of hydroxide of alkali metal and alkali metal silicate, and hydrate containing crystallisation water. System for producing a moulded article from a geopolymer includes a device for producing a mixture, a device for maintaining high pressure and a curing apparatus. Mixture production device is configured for production using at least first substance. Device to maintain high pressure is equipped with casting mould for holding mixture and configured to apply pressure, installed in moulding form.
EFFECT: curing unit is configured to hold a mixture subjected to direct pressing when using a device for maintaining high pressure, and is equipped with an air conditioner correcting the temperature of the atmosphere in the vicinity of the mixture.
