Several properties such as chemical compositions, specific surface areas, particle-size distributions and X-ray diffraction pattern of the ash were determined. The strength development of the concrete containing up to 45 % rice husk ash by weight of fhe total cementing material was also investigated. The following results were obtained. (1) The 7-day, 28-day and 91-day compressive strengths of the rice husk ash concrete were higher than those of the control concrete without rice hush ash.  (2) The 28-day maximum compressive strengths of the concretes were 54 MPa, 71 MPa and 87 MPa for the concretes with water-cementing material ratio was 50%, 40% and 30%, respectively.  (3) The dosage of superplasticizer in concrete increased as the ash content of the cementing material increased.","subitem_description_type":"Abstract"},{"subitem_description":"高強度コンクリート用混和材としての籾殻灰の利用について研究した。まず，実験に使用した籾殻灰の製造方\n法，基本物性，粉砕特性およびX線回折などの結果について述べた。つぎに，この籾殻灰と高性能AE減水剤\nを使用して水結合材比30％，40％および50％の高強度コンクリートを作製し，材齢7日，28日および91日に\nおいて強度試験を実施した。\n籾殻灰混入コンクリートの圧縮強度は，いずれの水結合材比および材齢においても，無混入コンクリートに比\nべて増大した。また，材齢28日の籾殻灰混入コンクリートの最大圧縮強度は，水結合材比30％，40％および50\n％において，それぞれ，87MPa，71MPaおよび54MPaとなり，高強度を示した。本研究結果から，籾\n殻灰は，高性能AE減水剤を使用することにより，高強度コンクリート用混和材として利用可能であることを\n確認した。","subitem_description_type":"Abstract"}]},"item_4_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学生物資源学部"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-0471","subitem_source_identifier_type":"PISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10073846","subitem_source_identifier_type":"NCID"}]},"item_4_subject_16":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"511","subitem_subject_scheme":"NDC"}]},"item_4_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Utilization of Rice Husk Ash as an Admixture in High-Strength Concrete"}]},"item_4_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"Agropedia提供データ"}]},"item_4_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper / 紀要論文"}]},"item_4_version_type_15":{"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":"石黒, 覚","creatorNameLang":"ja"},{"creatorName":"Ishiguro, Satoru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13146","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-18"}],"displaytype":"detail","filename":"AN100738460002204.pdf","filesize":[{"value":"544.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN100738460002204.pdf","url":"https://mie-u.repo.nii.ac.jp/record/5847/files/AN100738460002204.pdf"},"version_id":"6c5c0986-4147-4d68-8788-08250f85b2bc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Rice husk ash","subitem_subject_scheme":"Other"},{"subitem_subject":"Compressive strength","subitem_subject_scheme":"Other"},{"subitem_subject":"Concrete","subitem_subject_scheme":"Other"},{"subitem_subject":"Admixture","subitem_subject_scheme":"Other"},{"subitem_subject":"Superplasticizer","subitem_subject_scheme":"Other"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"高強度コンクリート用混和材としての籾殻灰の利用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"高強度コンクリート用混和材としての籾殻灰の利用","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"13","path":["465"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-04-26"},"publish_date":"2007-04-26","publish_status":"0","recid":"5847","relation_version_is_last":true,"title":["高強度コンクリート用混和材としての籾殻灰の利用"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-10-12T07:33:05.332432+00:00"}
