Under such conditions, concrete components suffer frost damage and steel corrosion. Model specimens of size 10×10×40 cm were developed ; these are suitable for rapid freez-thaw tests according to ASTM C 666, exposure testing, and load testing. Case studies were carried out in which many external factors. From the data obtained, an evaluation of the durability of concrete was induced by using a reliability function (R(t)). In the case of a water-cement ratio of 45 %,the reliability in the case of set-up ratio to initial ultimate strength becomes unreliable ? that is,the reliability falls below the assumed set-up ratio of 0.95 by neary 0.85%?at about 300 cycles.  In the case of a water-cement ratio of 45 %,the reliability in the case of set-up ratio to initial ultrasonic velocity becomes unreliable?that is, the reliability falls below the assumed set-up ratio of 0.90 by neary 70%?at about 300 cycles. Thus,the durability of cocrete is influenced by the number of freeze-thaw cycles.","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":"33814","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koichi, AYUTA"}],"nameIdentifiers":[{"nameIdentifier":"33815","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Noboru, SAEKI"}],"nameIdentifiers":[{"nameIdentifier":"33816","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kaneyoshi, OKADA"}],"nameIdentifiers":[{"nameIdentifier":"33817","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroaki, ARAI"}],"nameIdentifiers":[{"nameIdentifier":"33818","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroshi, SAKURAI"}],"nameIdentifiers":[{"nameIdentifier":"33819","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koichi, AYUTA"}],"nameIdentifiers":[{"nameIdentifier":"33820","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Noboru, SAEKI"}],"nameIdentifiers":[{"nameIdentifier":"33821","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kaneyoshi, OKADA"}],"nameIdentifiers":[{"nameIdentifier":"33822","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroaki, ARAI"}],"nameIdentifiers":[{"nameIdentifier":"33823","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":"25-1-8.pdf","filesize":[{"value":"3.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"25-1-8.pdf","url":"https://kitami-it.repo.nii.ac.jp/record/6703/files/25-1-8.pdf"},"version_id":"da8737a4-e14a-4534-bda6-ffb9bb0b614a"}]},"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":"The service life prediction of concrete in cold region by model specimen and reliability theory.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The service life prediction of concrete in cold region by model specimen and reliability theory."}]},"item_type_id":"2","owner":"1","path":["46"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-04-09"},"publish_date":"2007-04-09","publish_status":"0","recid":"6703","relation_version_is_last":true,"title":["The service life prediction of concrete in cold region by model specimen and reliability theory."],"weko_creator_id":"1","weko_shared_id":3},"updated":"2022-12-13T02:20:01.502174+00:00"}
