摘要： PROBLEM TO BE SOLVED: To provide a fine aggregate for a lightweight fire resistant concrete useful for producing the lightweight fire resistant concrete excellent in fire resistant properties. SOLUTION: The fine aggregate which contains moisture Wi inside, whose surface is covered with surface water Wo and whose diameter is 5 mm or less is obtained by removing and classifying ultra-fine particles by washing fine particulate ash. When the fine aggregate is dried at a temperature of 670-730°C, the surface water Wo is removed and voids S are generated by removing a part of the inside moisture Wi. When it is heated to 800-850°C, the ratio of an amorphous component is increased and the voids S which contain residual moisture inside is remained. The bubbles W at the surface layer of the fine aggregate are plugged with a coating material and furthermore a film C whose viscosity is increased by adding cement and water and by rising pH with OH - ion released from the cement is formed at the surface of the fine aggregate and finally the fine aggregate whose moisture content is 3-5 wt.% is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a fine aggregate for lightweight refractory concrete useful for producing lightweight refractory concrete having excellent refractoriness. SOLUTION: The removal of hyperfine particles by the cleaning of ash with a fine particle diameter and classification therefor are performed, thus a fine aggregate with a diameter of ≤5 mm in which the inside comprises moisture Wi and the surface is covered with surface water Wo is obtained. The fine aggregate is subjected to drying treatment at 670 to 730°C, so as to remove the surface water Wo and to generate each space S in which a part of the moisture Wi is removed at the inside. Thereafter, the same is subjected to heating treatment at 800 to 850°C to increase the ratio of amorphous components, and further, each space S including the remaining moisture is left at the inside. Thereafter, bubbles W on the surface layer of the fine aggregate is subjected to clogging treatment with a coating material. Further, cement and water are added thereto, so as to perform viscosity increasing treatment, and a coating C whose viscosity is made high by increasing pH by OH-ions released from the cement is formed on the surface of the fine aggregate. Finally, the fine aggregate having a water content of 3 to 5 wt.% is obtained. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：提供用于制造具有优异耐火性的轻质耐火混凝土的轻质耐火混凝土的细骨料。解决方案：通过清洁具有细颗粒直径和分级的灰分来除去超细颗粒，因此，内径为≤5mm的细集料，其中内部包含水分Wi并且表面被覆盖获得地表水Wo。在670〜730℃下对细骨料进行干燥处理，以除去表面水Wo，并产生其内部除去了一部分水分Wi的各空间S. 之后，在800〜850℃进行加热处理，以增加非晶质成分的比例，另外，将残留水分的空间S留在内部。之后，用涂料对该细骨料的表面层上的气泡W进行堵塞处理。此外，向其中加入水泥和水以进行增粘处理，并且在细骨料的表面上形成通过由从水泥释放的OH-离子增加pH而使粘度变高的涂层C. 最后，得到含水率为3〜5重量％的细骨料。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a fire-resistant coating structure of a base isolation device installed in a base isolation layer at an intermediate story of a building.
SOLUTION: A member having fire resistance is installed along the outer periphery of an upper face of a lower part structure. L-shaped hardware is attached to four corner positions on a lower face of a super structural body. A bolt hole for letting a shaft bolt which becomes a rotary shaft of a fire-resistant panel pass through is formed at an upper end position of a plane part of the L-shaped hardware. The fire-resistant panel provided with a nut is arranged between mutual L-shaped hardware. The shaft bolt inserted into the bolt hole of the L-shaped hardware is screwed into the nut to support the fire-resistant panel rotatably. An outer face part of the L-shaped hardware is covered with a fire-resistant block. Stopper hardware is attached to a part in the vicinity of a corner part of the L-shaped hardware or four corner positions on an inner side face of the fire-resistant panel in the super structural body.
