摘要
PURPOSE:To improve water-retainability by adding a flocculant to a slurry of inorganic fiber and ceramic raw material powder, forming the slurry into a block and sintering the block to obtain a ceramics. CONSTITUTION:An inorganic binder (e.g. polyester dispersion) is added and mixed to a suspension produced by suspending inorganic fiber (e.g. silica-alumina fiber) and ceramic raw material powder in water. The mixture is added with a flocculant to obtain a flocculated slurry containing the inorganic fiber and the ceramic raw material powder flocculated with each other. The slurry is formed into a block, which is calcined to form a ceramics and obtain the objective soil-improving material composed of porous fiber ceramics and having a porosity of 75-85%.
