Abstract: An active carbon molded body that comprises a plurality of active carbon granules that are foiled from aggregates of active carbon particles. The active carbon granules include a fibrous granulation binder. A plurality of communicating holes are foamed in the active carbon molded body. A pore size distribution curve obtained for the active carbon molded body by a mercury intrusion has: a first peak that is from first pores that are famed between active carbon particles; and a second peak that is from second pores that are foamed between active carbon particles and is for a smaller pore size than the first peak. The present invention thereby provides an active carbon molded body that has high water purification capacity and has a filtration flow rate that is at least a prescribed value.

Abstract: A fibrous granulation binder that is for active carbon granules that are formed from aggregates of active carbon particles and has a D50 particle size, as measured by laser diffraction, of 3.5-86.7 ?m. When a fibrous binder is used to produce active carbon granules, setting an appropriate particle size for the fibrous binder makes it possible to reliably produce high-strength active carbon granules.

Abstract: An active carbon molded body that comprises a plurality of active carbon granules that are formed from aggregates of active carbon particles. The active carbon granules include a fibrous granulation binder. The active carbon molded body is formed as a result of the plurality of active carbon granules being aggregated by means of the fibrous granulation binder in the active carbon granules. The present invention is also an active carbon molded body production method in which active carbon granules that have been formed by aggregating active carbon particles by means of a fibrous binder are molded by simultaneous application of heat and pressure without separate addition of a molding binder. The present invention thereby provides: an active carbon molded body that has high purification capacity and good production efficiency; and a production method for the active carbon molded body.

Abstract: Provided is a granular activated carbon which has a filtered flow rate of a predetermined value or higher, and a high water purification performance; and a method for manufacturing the same. A granular activated carbon comprises a plurality of activated carbon granules and a binder for binding the plurality of activated carbon granules, wherein the binder is composed of net-like fibers. Also, a method for manufacturing the granular activated carbon includes a step for spraying and drying slurry which is obtained by dispersing the activated carbon granules and the fibers in water.

Abstract: A moisture control construction material is enhanced in decorativeness and improved in stain-resistance by glazing the surfaces thereof. The material is prepared by mixing soil material and clay, molding the mixture to a body, applying glate on the body and firing the body. The body may be performed biscuit firing before glazing. The moisture-absorbing-and-desorbing-performance thereof in each 8-hour cycle is more than 80 g/m2. The body has prosity of 20-25%. More than 40% of pores of the body have a radius of less than 0.1 &mgr;m.

Abstract: A formed building material is provided of which front surface is allowed to be glazed, thereby improving its decorative property and improving its soil resistance and which has hazardous substance adsorbing function. This formed building material is produced by baking, a glaze is applied to a front surface of a main body of the formed building material, and the specific surface area of the main body is 10 m2/g or more. The main body has porosity of 20-50%, and more than 40% of pores of the main body have a radius of less than 0.1 &mgr;m. The glaze forms a glass layer on 90% or less of the entire surface area of the main body and/or the maximum thickness of the glass layer formed by the glaze is 300 &mgr;m or less. The formed building material is attached to a lower portion of a wall and/or a floor of a room.
