It was confirmed that the alkali stimulus of Ca(OH)2 contained in the KR slag could cause a cement-free binder to harden. However, the strength performance of a GGBFS-based cement-free binder mixed with only the KR slag was very low. The gypsum (CaSO4) is additionally used in order to enhance the strength performance of the GGBFS-KR slag binder. The result showed that the 28-day compressive strength of the GGBFS-KR slag-gypsum binder (GKGB) concrete was similar to that of slag cement. On the other hand, compared to those of slag cement, the drying shrinkage was shown to be 121.8?129.0%, and the cumulate porosity was shown to be 190?208%. These results imply that ettringite, which is a main hydrate of GKGB, is thick and provides the structural stability by forming a frame structure. However, the thicker ettringite, the more pores may be created. In other words, high amounts of ettringite form a porous structure, which has many micro pores so that the porosity and absorption become higher, leading to higher drying shrinkage.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_79_link_17":{"attribute_name":"出版者版へのリンク","attribute_value_mlt":[{"subitem_link_text":"10.1016","subitem_link_url":"https://doi.org/10.1016/j.conbuildmat.2016.07.023"}]},"item_79_link_5":{"attribute_name":"室蘭工業大学研究者データベースへのリンク","attribute_value_mlt":[{"subitem_link_text":"崔 亨吉","subitem_link_url":"http://rdsoran.muroran-it.ac.jp/html/100000220_ja.html"}]},"item_79_publisher_11":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier","subitem_publisher_language":"en"}]},"item_79_relation_18":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.conbuildmat.2016.07.023","subitem_relation_type_select":"DOI"}}]},"item_79_rights_19":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2016.
