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": "\u8457\u8005\u5225\u540d", "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": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u65e5\u672c\u6750\u6599\u5b66\u4f1a"}]}, "item_5_select_19": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "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": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u4f50\u3005\u6728, \u8b19\u4e8c"}], "nameIdentifiers": [{"nameIdentifier": "39736", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u4f50\u4f2f, \u7adc\u5f66"}], "nameIdentifiers": [{"nameIdentifier": "39737", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-30"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ZQ_56(8)_699-706.pdf", "filesize": [{"value": "1.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1000000.0, "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": "\u30ad\u30fc\u30ef\u30fc\u30c9", "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": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "C-S-H \u306e\u7d44\u6210\u304c\u30b3\u30f3\u30af\u30ea\u30fc\u30c8\u306e\u8010\u4e45\u6027\u306b\u53ca\u307c\u3059\u5f71\u97ff", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "C-S-H \u306e\u7d44\u6210\u304c\u30b3\u30f3\u30af\u30ea\u30fc\u30c8\u306e\u8010\u4e45\u6027\u306b\u53ca\u307c\u3059\u5f71\u97ff"}, {"subitem_title": "C-S-H \u306e\u7d44\u6210\u304c\u30b3\u30f3\u30af\u30ea\u30fc\u30c8\u306e\u8010\u4e45\u6027\u306b\u53ca\u307c\u3059\u5f71\u97ff", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["453/454", "423/424/425"], "permalink_uri": "http://hdl.handle.net/10191/17660", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2012-04-05"}, "publish_date": "2012-04-05", "publish_status": "0", "recid": "2912", "relation": {}, "relation_version_is_last": true, "title": ["C-S-H \u306e\u7d44\u6210\u304c\u30b3\u30f3\u30af\u30ea\u30fc\u30c8\u306e\u8010\u4e45\u6027\u306b\u53ca\u307c\u3059\u5f71\u97ff"], "weko_shared_id": null}
