摘要： PURPOSE:To improve performance by adding lime, silica sand, etc., to the incinerated ash of sewage sludge, specifying the ratio of calcium/silicon, adding an epoxy resin to globular slag obtained by crushing the melt by air and kneading and molding the slag. CONSTITUTION:Lime, silica sand, brick chips, LD slag, etc., are added to the incinerated ash of sewage sludge, and the ratio of calcium/silicon is brought to 1.0-2.0 at the conversion ratio of CaO/SiO2. The melt is crushed by high-speed air, thus forming globular air-crushed slag. The dye and pigment of an inorganic group, etc., and a polyvinyl alcohol derivative having an SiO2 reactive group shown in formula I are prepared. In formula, X, X and X represent an alkyl group, a hydrogen atom, a potassium atom, a sodium atom and an ammonium group. An epoxy resin is added to these substances, thus forming a proper quantity of inter-grain air gaps. The kneaded substance is poured into forms or spread all over a subbase course and rolled, and covered with a sheet for approximately twenty-four hours and cured, thus forming a color pavement slab. Accordingly, appearance, strength and water permeability can be improved while environmental contamination such as heavy metal eluation can be prevented, and incinerated ash can be utilized effectively.

摘要： PURPOSE:To improve the abrasion resistance of a formed body composed mainly of a powder produced by modifying vitreous blast-furnace slag powder with an alkaline aqueous solution or xonotlite, etc., by surface-finishing the formed body by flame-spraying process. CONSTITUTION:Powder of vitreous blast-furnace slag having a Blaine specific surface area of >=4,000cm /g is treated with an aqueous solution of an alkali such as NaOH having a concentration of >=0.5N at about 90 deg.C for >=30min to adjust the BET specific surface area to 20-140m /g by a glass-dissolution reaction and a hydration reaction. The treated product is washed with water and dehydrated by heating at about 250-800 deg.C to further increase the specific surface area. The surface-modified slag powder or its mixture with xonotlite, etc., is mixed with 3-20wt.% of a polymer additive, 1-20wt.% of synthetic pulp, 2-20wt.% of reinforcing fiber, proper amount of a cationic polymer flocculent and water to obtain a slurry. The slurry is formed by a paper-machine, etc., and dried by heating to obtain a porous formed body having a bulk density of 0.2-1g/cm . The objective light-weight formed body is produced by forming a coating film of 20-300mum thick on the surface by the plasma-spraying, etc., of a metal such as Al or a metal oxide such as SiO2 to the surface.

摘要： PURPOSE:To enhance the moisture adjustment properties by laminating air- permeable decorative material on the surface of an inorganic light-weight laminated product consisting mainly of powder obtained by modifying vitreous blast furnace slag powder qualitatively through glass fusion reaction and hydration reaction using an aqueous alkali solution. CONSTITUTION:The air-permeable decorative material of a thin layer is a thin layer product of natural wood, papers such as Japanese paper and sliding screen paper, cloth or unwoven cloth. First, a mixture of surface reforming slag powder(or slurry containing said powder), polymer mixing agent and water is kneaded. If reinforcing fiber, coagulant, synthetic pulp, calcium silicate hydrate, light-weight aggregate, thickener, dispersant and water-curable gypsum are to be added, these should be added prior to or during kneading process. The air-permeable decorative material is placed over the slurry obtained by kneading and pressed. After molding, the decorative material is laid at the bottom of a mold such as a die frame from the viewpoint of ease of operation. then the slurry is poured over the decorative material and dehydrated under pressure and molded as the most suited manufacturing method.
