METHOD OF PRODUCING HARDENED BODY
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
【課題】セメント材を用いずに建設用資材としての強度を確保できる硬化体の製造方法の提供。【解決手段】アルカリ溶液とケイ素粉末またはシリカフュームとを所定時間、撹拌することにより、アルカリ溶液中にケイ素粉末(又はシリカフュ—ム)を均一に分散させて、当該スラリーを用いた硬化体で所望の圧縮強度を得ることができる。具体的には、濃度３ｍｏｌ／Ｌの水酸化カリウム溶液と粒径４〜１０μｍのケイ素粉末とを１２〜２４時間、攪拌し、スラリーを得る工程と、フライアッシュと、前記スラリーとを混合した材料を硬化させ、硬化体を得る工程とを有する硬化体の製造方法。【選択図】図１
