Title:
シリカ含有泥土スラッジからなる単粒度骨材を用いた透水性ブロック
Document Type and Number:
Japanese Patent JP4514935
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently manufacture monodisperse grain size aggregate capable of being used as a water permeable block or the like by using silica-containing mud sludge usually having a fine particle size of 75 μm or less and to effectively put silica-containing mud sludge (sludge cake) to practical use. SOLUTION: The method for manufacturing monodisperse grain size aggregate comprising silica-containing mud sludge includes a mixing process for obtaining a mixture with a water content of 15-25% by adding 3-15 mass % of a calcium compound to silica-containing mud sludge, a granulation process for obtaining a granulated product by granulating the mixture being a raw material, a hydrothermal solidifying process for obtaining solidified matter by solidifying the granulated product by hydrothermal treatment and a screening process for obtaining monodisperse grain size aggregate having a predetermined particle size range by screening the solidified matter.
