FIBER-REINFORCED CONCRETE CAPABLE OF RECYCLING MATERIAL, AND RECYCLING METHOD THEREOF
To provide a fiber-reinforced concrete capable of recycling a material capable of exhibiting material properties required as a housing material in service and of being separated and regenerated after the service.SOLUTION: A fiber-reinforced concrete 1 capable of recycling a material is made by putting a metallic fiber-reinforced material 3 having a low melting point into a hardened body 2 of a compound, the compound being formed by adding some or all of materials, such as a fine aggregate, a coarse aggregate and an admixture, to a binder agent comprising some or all of cement, an admixture and water. Preferably a metal fiber comprising an alloy or an element metal is used as the metallic fiber-reinforced material 3 having low melting point, the alloy mainly comprising aluminum, bismuth, cesium, mercury, potassium, lithium, sodium, lead, rubidium, tin, zinc, indium, gallium, cadmium, and their oxide. Moreover the fiber-reinforced concrete after service can be separated into a metal fiber and a cement-hardened body and be regenerated through low-temperature heating process or the like, and can thereby be recycled.SELECTED DRAWING: Figure 1
【課題】供用中は建材として必要な材料特性を発揮しつつ、供用済み後は分離再生ができる材料のリサイクルが可能な繊維補強コンクリートを提供する。【解決手段】材料のリサイクルが可能な繊維補強コンクリート１は、セメント、混和材料、水の一部又はすべてからなる結合剤に、細骨材、粗骨材、混和材料といった材料の一部或いは全部を添加して構成した配合物の硬化体２に、融点の低い金属製の繊維補強材３を混入してある。この融点の低い金属製の繊維補強材３としては、アルミニウム、ビスマス、セシウム、水銀、カリウム、リチウム、ナトリウム、鉛、ルビジウム、錫、亜鉛、インジウム、ガリウム、カドミウムやこれらの酸化物を主材料として含む合金或いは単体金属からなる金属繊維が好適である。また、供用済み後の繊維補強コンクリートは、低温の加熱処理等により、金属繊維とセメント硬化体の分離・再生が可能となり、リサイクルできる。【選択図】図１
