The objective of this study is to visualize cross sections of the surface layers of concrete at different finishing times using electron microscopy imaging. For the first image, an area roughly 1.5 mm deep from the surface of the concrete was observed using a scanning electron microscope. When the concrete surface was finished and after the bleeding of water had stopped, the surface was smooth and no large voids or cracks were observed in the surface layer in the electron microscope image. In the image, the concrete surface layer was bright, and it was observed that the structure of the surface layer was dense. The second image is of high strength concrete. High strength concrete was difficult to finish at the initial setting time. Even after the bleeding of water had stopped, the surface of the concrete was hard, making the concrete difficult to finish. When finished at the initial setting time of the concrete, the surface was not smooth, and large voids and cracks were observed in the surface layer shown in the electron microscope image.","subitem_description_type":"Abstract"}]},"item_10002_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本研究では，仕上げ時期の異なるコンクリートの表層の状態を把握することを目的として，走査型電子顕微鏡（以下，SEMと称す）により表層部の断面を可視化し観察を行った．","subitem_description_type":"Other"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"学校法人ものつくり大学"},{"subitem_publisher":"Institute of Technologists"}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"ものつくり大学"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.iot.ac.jp/","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2185-3746","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"澤本, 武博"},{"creatorName":"サワモト, タケヒロ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"228","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"沢木, 大介"},{"creatorName":"サワキ, ダイスケ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"742","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"青山, 一真"},{"creatorName":"アオヤマ, カズマ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"782","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"樋口, 正典"},{"creatorName":"ヒグチ, マサノリ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"783","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"臺, 哲義"},{"creatorName":"ダイ, アキヨシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"744","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SAWAMOTO, Takehiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"181","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SAWAKI, Daisuke","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"747","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"AOYAMA, Masanori","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"826","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"HIGUCHI, Masanori","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"748","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"DAI, Akiyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"749","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":"2023-03-08"}],"displaytype":"detail","filename":"bulletin_182.pdf","filesize":[{"value":"2.8 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"仕上げ時期が異なるコンクリート表層部の 走査型電子顕微鏡による硬化組織観察","url":"https://iot.repo.nii.ac.jp/record/282/files/bulletin_182.pdf"},"version_id":"6bcc49cf-2b61-4298-ac07-96d863de1550"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"コンクリート床版","subitem_subject_scheme":"Other"},{"subitem_subject":"仕上げ","subitem_subject_scheme":"Other"},{"subitem_subject":"査型電子顕微鏡","subitem_subject_scheme":"Other"},{"subitem_subject":"反射電子像","subitem_subject_scheme":"Other"},{"subitem_subject":"Concrete Slab","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Finishing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Scanning electron microscope","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Backscattered electron image","subitem_subject_language":"en","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":"仕上げ時期が異なるコンクリート表層部の 走査型電子顕微鏡による硬化組織観察","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"仕上げ時期が異なるコンクリート表層部の 走査型電子顕微鏡による硬化組織観察"},{"subitem_title":"Scanning Electron Microscope Observation of Hardened Concrete Surface at Different Finishing Time","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"11","path":["30"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-03-08"},"publish_date":"2023-03-08","publish_status":"0","recid":"282","relation_version_is_last":true,"title":["仕上げ時期が異なるコンクリート表層部の 走査型電子顕微鏡による硬化組織観察"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2024-03-01T07:08:01.390242+00:00"}
