珊瑚砂混凝土耐久性及应用技术研究进展

摘要

综述了珊瑚砂混凝土的应用研究及进展.对影响珊瑚砂混凝土耐久性的因素进行了分析,制约其应用的主要因素为高孔隙渗透性导致的内部结构筋腐蚀,以及珊瑚砂自身强度较低.针对以上两方面,重点总结了珊瑚砂混凝土用加强筋材料及珊瑚砂改性技术研究进展情况,最后对珊瑚砂混凝土的发展趋势进行了展望.研究分析结果可为珊瑚砂制备混凝土在远海岛礁建设的应用提供借鉴.%In this paper, application research and progress of coral concrete were interpreted. Factors influencing durability of coral concrete were analyzed. The corrosion of rebar and the lower strength of coral itself were the two main constraints. Re-ferring to mentioned two aspects, the studies of rib materials and coral modification were especially summarized. In the end, the prospect of coral concrete application was illustrated. The research result could provide reference for application of coral con-crete to basic constructions on offshore islands.
