C-S-Hの機械的特性に及ぼす老化の影響を解明するために、以前に実施した131日前のC3Sペーストに関するPDF解析結果との比較も行った。53年前のC3Sペーストは、131前のものよりも全体的な弾性率が高く、圧縮応力に対する耐性が優れていました。さらに、53年前のC3Sペーストのマクロなひずみは、マクロスケールでのマイクロクラックなどの機械的変形によって引き起こされたと考えられる。結果は、初期および後期におけるC-S-Hの原子レベルおよびメソスケールでの機械的挙動について実験的な証拠を提供する。\n","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.conbuildmat.2019.117714","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/pii/S0950061819331678","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0950-0618","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata
