The invention discloses island reef modified coral aggregate UHPC, a preparation method thereof and an island reef prefabricated part. The modified coral aggregate UHPC is prepared by mixing the following raw materials in parts by mass: 30 to 50 parts of cement, 5 to 15 parts of ion migration inhibitor, 40 to 60 parts of modified coral aggregate, 3 to 7 parts of stainless steel fiber, 0.4 to 0.8 part of indented polyethylene fiber, 0.3 to 0.7 part of water reducing agent, 0.5 to 1.5 parts of rubber powder, 0.05 to 0.15 part of defoaming agent, 1 to 3 parts of combined expanding agent, 0.5 to 1.5 parts of early strength agent, 0.1 to 0.2 part of carbon fiber, 0.05 to 0.1 part of carbon nano tube and 9 to 12 parts of mixing water. The prepared modified coral aggregate UHPC has the advantages of self-compaction, high strength, high toughness, high durability and high electromagnetic shielding property, local materials can be used, island prefabricated members such as fish reefs and offshore platforms can be prepared from the modified coral aggregate UHPC, and the requirements of island engineering construction and use are met.

    本发明公开了一种岛礁改性珊瑚骨料UHPC及其制备方法、岛礁预制件。改性珊瑚骨料UHPC按质量比计,由以下原料混合而成:水泥,30~50份,离子迁移抑制剂,5~15份,改性珊瑚骨料,40~60份,不锈钢钢纤维,3~7份,刻痕聚乙烯纤维,0.4~0.8份,减水剂,0.3~0.7份,胶粉,0.5~1.5份,消泡剂,0.05~0.15份,组合膨胀剂,1~3份,早强剂,0.5~1.5份,碳纤维,0.1~0.2份,碳纳米管,0.05~0.1份,拌和水,9~12份。本发明制得的改性珊瑚骨料UHPC具有自密实、高强度、高韧性、高耐久及高电磁屏蔽性,并且能够就地取材,并由此制得鱼礁、海上平台等岛礁预制件,满足岛礁工程建设和使用需求。
