GEOPOLYMER COMPOSITION MANUFACTURING METHOD

WIPO Patent Application WO/2024/048682

A1

Provided is a geopolymer composition manufacturing method that does not cause deterioration of strength development even in the case in which an alkaline solution added in a manufacturing step is replaced with an alkaline powder and water.　The method is configured: so as to include an alkaline-powder pulverizing step in which all or a portion of an aggregate is introduced into a mixer first, water employing a portion or all of kneading water as a primary water volume is added to and mixed with the aggregate such that the water is uniformly held at a surface of the aggregate in the mixer, and an alkaline powder is added to and mixed in the mixer to pulverize the alkaline powder; and so that a geopolymer composition is generated by adding and mixing remainder materials containing an active filler after the alkaline-powder pulverizing step. Therefore, the alkaline powder is finely pulverized in the alkaline-powder pulverizing step, the specific surface area thereof is increased, and thus, it is possible to increase the rate at which the alkaline powder dissolves in water. Accordingly, it is possible to increase the chemical reaction rate.
