Specifically, anti-frost-damage to concrete caused by CMA (Calcium Magnesium Acetate) and NaCl when they were used as de-icing agent were studied by investigating past researches, conducting substantiation tests and analyzing the resultant data. The main causes of deterioration were clarified and an appropriate deterioration prediction equation was thus obtained.", "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": "SAKURAI, Hiroshi"}], "nameIdentifiers": [{"nameIdentifier": "34010", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "AYUTA, Koichi"}], "nameIdentifiers": [{"nameIdentifier": "34011", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "OKADA, Kaneyoshi"}], "nameIdentifiers": [{"nameIdentifier": "34012", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "SATO, Iwao"}], "nameIdentifiers": [{"nameIdentifier": "34013", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "SAKURAI, Hiroshi"}], "nameIdentifiers": [{"nameIdentifier": "34014", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "AYUTA, Koichi"}], "nameIdentifiers": [{"nameIdentifier": "34015", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "OKADA, Kaneyoshi"}], "nameIdentifiers": [{"nameIdentifier": "34016", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "SATO, Iwao"}], "nameIdentifiers": [{"nameIdentifier": "34017", "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", "download_preview_message": "", "file_order": 0, "filename": "29-1-3.pdf", "filesize": [{"value": "2.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2300000.0, "url": {"label": "29-1-3.pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/6742/files/29-1-3.pdf"}, "version_id": "5d059bbc-3106-4c85-ba59-002f76eb224a"}]}, "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": "Study on the relationship between de-icing material and concrete durability", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Study on the relationship between de-icing material and concrete durability"}]}, "item_type_id": "2", "owner": "1", "path": ["50"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/6742", "pubdate": {"attribute_name": "公開日", "attribute_value": "2007-04-09"}, "publish_date": "2007-04-09", "publish_status": "0", "recid": "6742", "relation": {}, "relation_version_is_last": true, "title": ["Study on the relationship between de-icing material and concrete durability"], "weko_shared_id": 3}
