The physical and chemical properties of the lightweight concrete specimens and those of the mortar specimens were examined. The results are as follows : (1) The lightweight concrete specimen contained more salt than the same mortar specimen. (2) The free calcium content on the surface of lightweight concrete specimens tended to decrease more than that of the mortar specimen. (3) Ettringite by sulfuric ion and Friedel’s salt by chlorine ion were not observed in either the lightweight concrete specimens or the mortar specimens.","subitem_description_type":"Abstract"}]},"item_2_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"北見工業大学"}]},"item_2_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hiroshi, SAKURAI"}],"nameIdentifiers":[{"nameIdentifier":"33659","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koichi, AYUTA"}],"nameIdentifiers":[{"nameIdentifier":"33660","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Noboru, SAEKI"}],"nameIdentifiers":[{"nameIdentifier":"33661","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshio, FUJITA"}],"nameIdentifiers":[{"nameIdentifier":"33662","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Seiji, KANEKO"}],"nameIdentifiers":[{"nameIdentifier":"33663","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mikito, IKEDA"}],"nameIdentifiers":[{"nameIdentifier":"33664","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":"2016-11-22"}],"displaytype":"detail","filename":"23-1-3.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"23-1-3.pdf","url":"https://kitami-it.repo.nii.ac.jp/record/6674/files/23-1-3.pdf"},"version_id":"ca485181-e3e5-493b-98ba-ea9a6449e835"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Durability of Lightweight Concrete and Mortar Exposed under Some Environment","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Durability of Lightweight Concrete and Mortar Exposed under Some Environment"}]},"item_type_id":"2","owner":"1","path":["44"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-04-09"},"publish_date":"2007-04-09","publish_status":"0","recid":"6674","relation_version_is_last":true,"title":["Durability of Lightweight Concrete and Mortar Exposed under Some Environment"],"weko_creator_id":"1","weko_shared_id":3},"updated":"2022-12-13T02:20:01.088394+00:00"}
