In future, this type of basic oxygen furnace slag is anticipated to replace the conventional basic oxygen furnace slag. The objective of this study was to the applicability of this powdered basic oxygen furnace slag as a subbase material. Firstly, the changes in physical and chemical properties, the surface texture and the hydrated products of the basic oxygen furnace slag naturally weathered outdoors were determined by X-ray diffraction, differential thermal analysis (DTA) and SEM-EDXA analysis. Secondly, the strength test, the CBR test and the expansion test of the compacted basic oxygen furnace slag mixtures were carried out in order to clarify the strength characteristics of the powdered basic oxygen furnace slag as a subbase material and the effect of weathering outdoors on reducing its unfavorable self-deterious properties. The main results obtained are summarized as follows; (1) The major compounds of the powdered basic oxygen furnace slag were β-C_2S, C_2F, C_2S-C_3P, Wustite and a considerably large amount of f-Cao and Ca(OH)_2. (2) In the powdered basic oxygen furnace slag naturally weathered outdoors, the hydration of β-C_2S and f-Cao slowly progressed with age, resulting in the formation of C-S-H gel, Ca(OH)_2 and CaCO_3 on the surface of particles. (3) The powdered basic oxygen furnace slag became a stable material not showing self-deterious property by weathering outdoors for about three months, and thus it can be used as a subbase material.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域環境デザイン学系","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本材料学会"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002295735/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本材料学会；本文データは日本材料学会の許諾に基づきCiNiiから複製したものである"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00096175","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0514-5163","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"島居, 和之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川村, 満紀"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"枷場, 重正"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"五十嵐, 心一"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"TE-PR-TORII-K-375.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-TORII-K-375.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/8278/files/TE-PR-TORII-K-375.pdf"},"version_id":"becc8e45-3096-4ab9-91bb-47194518ce31"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"粉化転炉スラグの路盤材料としての利用に関する基礎的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"粉化転炉スラグの路盤材料としての利用に関する基礎的研究"},{"subitem_title":"Fundamental Study on Utilization of Powdered Basic Oxygen Furnace Slag as Subbase Material","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["936"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"8278","relation_version_is_last":true,"title":["粉化転炉スラグの路盤材料としての利用に関する基礎的研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T02:11:18.645098+00:00"}
