摘要： PROBLEM TO BE SOLVED: To provide a melting treatment method for waste and hazardous matter which has solved problems arising from a flux of an additive in a melting treatment for the waste and hazardous matter. SOLUTION: This melting treatment method for waste and hazardous matter comprises a process of adding an electric furnace reduction slag to the waste and hazardous matter to be subjected to a melting treatment for heating treatment, and the amount of addition preferred to be 10-100% mass. Granulation after adding the waste and hazardous matter and the electric furnace reduction slag both of which are in powder conditions by an addition amount of 10-100% mass is effective. Further, an addition by an addition amount of 10-100% mass after granulating the electric furnace reduction slag is effective.

摘要： PROBLEM TO BE SOLVED: To produce a high-quality inexpensive coal ash granulated material by combining industrial wastes each having a low rate of utilization. SOLUTION: Electric furnace reduction slag is added to coal ash by 10-100% of the mass of the coal ash and a mixture is prepared in a mixer 1, sent to a mixing-kneading machine 3 through a stock hopper 2, kneaded with water and granulated with a granulator 5 to produce the objective coal ash granulated material. Strength is exhibited by comminuting the electric furnace reduction slag to a particle diameter equal to that of the coal ash before addition to the coat ash, and the production of the coal ash granulated material is facilitated by adding 1-5% bentonite based on the amount of the coal ash to the mixture.

摘要： PROBLEM TO BE SOLVED: To obtain a sulfur composition less liable to fire, containing a uniformly dispersed filler and used for obtaining a high density and high strength hardened body by mixing sulfur and a mineral powder in a specified weight ratio at a specified temperature. SOLUTION: Sulfur and a mineral powder are mixed in a weight ratio of 1:(1-4) at 120-160 deg.C to obtain the objective sulfur composition. Part of the mineral powder may be substituted by an aggregate, preferably a fine aggregate for concrete and the temperature of the sulfur is preferably 120-160 deg.C. A hardened body of the sulfur composition consists of sulfur and the mineral powder as a filler. The sulfur may be powdery or flaky free sulfur or molten sulfur and sulfur obtained as a byproduct in an oil refining step or sulfur commercially available as a reagent may also be used.

摘要： PROBLEM TO BE SOLVED: To increase bulk density to facilitate storage and conveyance and, at the same time, facilitate, handling by pressure-molding cement fly ash by a continuous roll pressure-molding process. SOLUTION: Cement fly ash recovered from a gas discharged from a kiln is supplied to a continuous roll pressure-molding device. That is, first, the cement fly ash is vibrated and deaerated and then is pressed into flakes between a pair of rotary rolls. According to a calculation of the density of the molded flakes based on the pressed-out dimensions and the mass of the moldings, the density is 1.7 g/cm3, 1.8 g/cm3 and 1.9 g/cm3, respectively to the space between rolls of 3 mm, 5 mm and 7 mm. Thus, the fine moldings are obtained by widening the space. In addition, the measurements of the bulk density of the moldings shredded by a shredder are 0.75 g/cm3, 0.82 g/cm3 and 0.90 g/cm3 to the space between the rolls of 3 mm, 5 mm and 7 mm, respectively. The results indicate that the bulk density increases in proportion to an increase in the widened space between the rolls, that is, a value of 4-5 times compared with the density before the pressure-molding.

摘要： PROBLEM TO BE SOLVED: To obtain fly ash that is prevented from producing dust without adding an additional constituent other than water, does not form a rigid solid body and can be easily turned into a powder by adding water to fly ash particles having a particle size not smaller than a specified diameter. SOLUTION: Fly ash particles, which are combustion ash of coal, usually have a particle size distribution of up to 30 μm. When such a fly ash is treated, that is, in collection, transportation, storage and other works before and after combustion, a fly ash powder, that easily produces dust as it is, is used as a raw powder. Water is added to the fly ash raw powder having particle sizes not smaller than 5 μm. That is, the fly ash raw powder is classified and fine particle part, i.e., particles having particle sizes smaller than 5 μm are removed. Then water is added to the fly ash particles by spraying or other means. By this method, dust is prevented from being generated and fly ash that can easily be turned into powder is obtained.

摘要： PROBLEM TO BE SOLVED: To obtain an admixture for concrete having high fluidity, a rapid hardening rate and improved strength-manifesting properties in mid/long term by making the concrete composition include one or more kinds of municipal waste-burned ash and sewage sludge-burned ash, and gypsum. SOLUTION: This admixture for concrete having 0.075-0.15 mm particle diameter is obtained by pulverizing a clinker obtained by firing a municipal waste, or a sewage sludge powder obtained by mixing shells and a sewage sludge with lime to provide a fired product containing 10-40 wt.% one or more kinds of compounds selected from among C11 A7 CaCl2 , C11 A7 CaF2 and C3 A, and one or more kinds selected from among C2 S and C3 S, adding lime to the obtained fired product, and pulverizing and classifying the fired product with the added lime. The concrete composition is obtained by blending 100 pts.wt. cement, 20-60 pts.wt. admixture for the concrete, 37-42 pts.wt. water, and
