Concrete durability depends on the physical and chemical properties of concrete. The physical and chemical properties of concrete are affected by the kinds and amounts of hydration products. C-S-H is dominant hydration product. And, Ca/Si ratio of C-S-H depends on types of mineral admixtures, mixture proportion and curing period. Therefore, it is important for estimating of concrete durability to clarify the properties of C-S-H. In this study, physical properties, such as density and surface area, of C-S-H with various Ca/Si ratios were measured. And chemical properties, such as chloride binding capacity and releasing due to carbonation were also measured. From the experimental results, physical and chemical properties of C-S-H depend on Ca/Si ratio. Based on these results, the effect of Ca/Si ratio of C-S-H on concrete durability, such as chloride diffusion and chloride binding was examined. The durability of blended cement concrete can be explained qualitatively in consideration of Ca/Si ratio of C-S-H.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"39738","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sasaki, Kenji"}]},{"nameIdentifiers":[{"nameIdentifier":"39739","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Saeki, Tatsuhik"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本材料学会"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00096175","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05145163","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐々木, 謙二"}],"nameIdentifiers":[{"nameIdentifier":"39736","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐伯, 竜彦"}],"nameIdentifiers":[{"nameIdentifier":"39737","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":"2019-07-30"}],"displaytype":"detail","filename":"ZQ_56(8)_699-706.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ZQ_56(8)_699-706.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2912/files/ZQ_56(8)_699-706.pdf"},"version_id":"c494eb10-6b01-4fe0-8493-fb447814a8f8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"C-S-H","subitem_subject_scheme":"Other"},{"subitem_subject":"Ca/Si ratio","subitem_subject_scheme":"Other"},{"subitem_subject":"Density","subitem_subject_scheme":"Other"},{"subitem_subject":"Surface area","subitem_subject_scheme":"Other"},{"subitem_subject":"Chloride diffusion","subitem_subject_scheme":"Other"},{"subitem_subject":"Chloride binding","subitem_subject_scheme":"Other"},{"subitem_subject":"Carbonation","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"C-S-H の組成がコンクリートの耐久性に及ぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"C-S-H の組成がコンクリートの耐久性に及ぼす影響"},{"subitem_title":"C-S-H の組成がコンクリートの耐久性に及ぼす影響","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-04-05"},"publish_date":"2012-04-05","publish_status":"0","recid":"2912","relation_version_is_last":true,"title":["C-S-H の組成がコンクリートの耐久性に及ぼす影響"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:06.770098+00:00"}
