摘　　要：对用海水拌养珊瑚礁、砂混凝土修补与抢修远离大陆的岛礁损坏工程进行应用研究和调研,对该种混凝土的原材料和物理力学性能进行检测,研究了修补界面剂的配合比与修补工艺以及操作方法,并进行了海水拌养珊瑚礁、砂混凝土与海水拌养普通混凝土修补的粘结强度对比测试和海水拌养快凝快强混凝土快速抢修的工程应用实践检验,为岛礁工程修补和抢修提供技术参考资料。Applications of coral-sand concrete mixed with seawater are studied for quickly restoring the destoryed patches in reef engineering far away from the main land. The raw materials and their mechanical properties are tested. Also researches on the interfacial cement＇s proportioning, mending techniques, and practical operation are conducted. In addition, adhesive strengths respectively of the coral-sand concrete with seawater and ordinary concrete with seawater are compared with each other in the mending tests. Seawater concrete with its fast concreting and instantly strengthening are also tested in engineering practice for providing reference for reef island mending.
