ABSTRACT:
This invention aims to provide an inorganic porous body which can be ensured with high strength and high porosity and which is applicable to soil conditioners. The inorganic porous body has a pellet-shape, having pores, includes 50% and more silica by weight, and 20% and more alumina by weight. Also, the inorganic porous body has a porosity of 40% and more by volume. The sludge, which discharged from casting foundries as sludge-wastes and which has an ignition loss of 20%, is utilized as a starting material. The starting material is mixed with water to make a mixture, the mixture is formed to become pellets, and the pellets are burned.
