  • Patent number: 11560335
    Abstract: To provide a molded body which has high strength, high ductility, and excellent dimensional stability while maintaining incombustibility and fire resistance. A molded body formed from a curable composition containing (A) at least one aluminosilicate source, (B) an alkali metal hydroxide, (C) a calcium ion source, and (D) an alkali resistant fiber, wherein the aluminosilicate source (A) has an SiO2 content of 50% by mass or more based on a total mass of the aluminosilicate source (A), an amorphous ratio of 50% by mass or higher, and an average particle diameter of 50 ?m or smaller, and comprises an aluminosilicate source having an average particle diameter of 10 ?m or smaller in an amount of 30% by mass or more based on the total mass of the aluminosilicate source (A).

  • Patent number: 10851545
    Abstract: A concrete tile comprising a tile body, the tile body having an upper face hardened through non-mold shaping, a lower face hardened through mold shaping, and a side surface that includes a cut end face in at least one side of the tile body, wherein the tile body contains alkali-resistant fiber in an entire thickness thereof in a state substantially free of fiber-containing granular bodies; the alkali-resistant fibers comprise at least one member selected from the group consisting of polyvinyl alcohol-based fibers, polyethylene fibers, polypropylene fibers, acrylic fibers, and aramid fibers; and a flexural strength of a 30 mm×150 mm sized cut piece of the tile body is not less than 6 N/mm2.
