摘　　要：通过对海水拌养混凝土耐海水侵蚀试验和海水中化学成分对水泥胶砂与骨料的影响分析,以及海水拌养混凝土的工程应用与调查结合长龄期强度跟踪观测,研究了海水拌养素混凝土的耐久性。旨在为淡水资源匮乏的海岛工程建设应用海水拌养混凝土,减少从大陆船运施工用淡水,节省工程投资提供资料。In the test of resisting seawater erosion, the durability of plain seawater concrete was studied considering the influence of seawater chemical composition on cementing ability, cement and sand. Furthermore, a long-term strength observation was carried out in its project ap- plication. We can substitute seawater concree with coral, broken stone or fiver sand for freshwater concrete if construction quality , reasonable proportions and compact structure can be ensured. As fresh water is in very short supply, this technique can help island projects save invest- ment by shipping less fresh water from mainland.
