Document Type and Number:
Japanese Patent JP6686693
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of producing a hardened body capable of securing strength as a construction material without using a cement material.SOLUTION: A silicon powder (or silica fume) is uniformly dispersed in an alkaline solution by stirring an alkali solution and the silicon powder or silica fume for a predetermined time to obtain a desired compressive strength in a hardened body using the slurry. More specifically, a method of producing a hardened body includes the steps of; stirring a potassium hydroxide solution having a concentration of 3 mol/L and a silicon powder having a particle size of 4-10 μm for 12-24 h to obtain slurry; and hardening a material obtained by mixing fly ash and the slurry to obtain the hardened body.SELECTED DRAWING: Figure 1
