Abstract

To provide a method for producing a geopolymer foam capable of forming desired bubbles while maintaining the strength of the geopolymer foam by using a specific aggregate and adjusting the physical properties of a reaction slurry to specific conditions.SOLUTION: There is provided a method for producing a geopolymer foam, wherein a reaction slurry that contains an aluminosilicate, an alkali metal silicate, aggregate and water is obtained, and a foaming agent is added to the reaction slurry to form an expandable slurry, and the expandable slurry is heated to form a geopolymer foam. This method for producing a geopolymer foam is characterized in that: mica which has an average particle diameter of 50 to 500 μm and a volume ratio (X) of particles having a particle diameter of 10 μm or less of 3% or less is used as the aggregate; and the reaction slurry has a viscosity of 3,000 to 15,000 mPa s at 23°C.SELECTED DRAWING: None
