And there are the concretes having equally high strength as the ordinary crushed stone concretes have. 2.The quantitative study of bleeding are made: the rates of bleeding can be reduced a little by using AE agents, but the quantity of bleeding can be reduced some. This tendency is almost the same in the crushed stone concretes, but the bleeding of Coral finger concretes is much largerer in quantity and much more rapid than that of the crushed stone concretes. 3.The young\u0027s modulus of the Coral finger concrete is considerablly lower than that of the crushed stone concrete, and the value of it is higher than or about the same as the values specified in the specification. 4.The reference table of mix proportionning of Coral finger concretes are presented, which can be served as the standards in trial mixes of Coral finger concrete work.", "subitem_description_type": "Other"}, {"subitem_description": "紀要論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "琉球大学理工学部"}, {"subitem_1522300295150": "en", "subitem_1522300316516": "Science and Engineering Division, University of the Ryukyus"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/23951"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0387-429X"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250785"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "琉球大学理工学部紀要. 工学篇"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "Bulletin of Science \u0026 Engineering Division, University of the Ryukyus.
