The pore structure was quantitatively evaluated by some parameters derived from the spatial statistical functions. There exists a good correlation between the coarse capillary pore structures and the electrical conductivity. The coarse capillary porosity and its spatial correlation distances do not contradict the total capillary porosity and pore connectedness which is induced from the FKG inequality. It is suggested that connectedness of invisible fine pores is also an increasing function of the fine porosity. In spite of the incorporation of mineral admixtures, the electrical conductivity of the pastes with the admixtures could be expressed with the same liner regression lines as the plain cement pastes without the admixtures. Furthermore, the incorporation of fly ash and silica fume did not decrease the continuity of coarse capillary pores. Nevertheless, the electrical conductivity decreased in the cement pastes with those admixtures. This fact suggests that more disconnected networks of fine capillary pores were generated in the cement pastes containing the mineral admixtures even if the total porosity was the same as the plain system without them.","subitem_description_type":"Abstract"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会 = Japan Society of Civil Engineers"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2208/jscejmcs.67.462","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/browse/jscejmcs","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jsce.or.jp/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 2011 公益社団法人 土木学会 Japan Society of Civil Engineers"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2185-6567","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"内藤, 大輔"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"五十嵐, 心一"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"柴山, 舞"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"TE-PR-IGARASHI-S-462.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-IGARASHI-S-462.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/8333/files/TE-PR-IGARASHI-S-462.pdf"},"version_id":"627c53e4-3947-43c0-a2ce-efd71d56ddcf"}]},"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":"セメント硬化体中の毛細管空隙空間構造と電気伝導率の対応","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"セメント硬化体中の毛細管空隙空間構造と電気伝導率の対応"},{"subitem_title":"Relationship between capillary pore spatial structure and electrical conductivity in cement pastes","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["936"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"8333","relation_version_is_last":true,"title":["セメント硬化体中の毛細管空隙空間構造と電気伝導率の対応"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T02:10:23.440889+00:00"}
