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.

内容記述 | The Kambara reactor (KR) slag, which is a byproduct generated in the preliminary treatment process of molten iron by a KR mechanical stirring process, is composed of Ca(OH)2, CaCO3 and 2CaO・SiO2. 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. | |||||
