摘　　要：为解决陆地资源紧缺等问题,与普通混凝土力学性能相近的珊瑚混凝土成为近年来研究的新型材料,随着对珊瑚混凝土不断深入研究,发现在其制备过程中存在很多的缺陷,如珊瑚石的自身强度低、抗渗性能差、易遭受海水中氯盐的侵蚀、与钢筋的粘结程度低等,因此对国内外已有的珊瑚混凝土改性处理技术的研究成果进行了归纳,此外还总结出当前对珊瑚材料作用机理的局限性以及对珊瑚混凝土改性处理方法、动态力学性能的研究存在的不足,为后续研究提供参考。In order to solve the shortage of land resources and other problems,coral concrete with similar mechanical properties to ordinary concrete has become a new material studied in recent years.With the continuous in-depth study of coral concrete,it is found that there are many defects in its preparation process:For example,coral stone has low strength,poor impermeability,easy to be eroded by chlorine salts in seawater,and low bonding degree with steel bars.Therefore,the existing research results of coral concrete modification treatment technology at home and abroad are summarized.In addition,the limitations of the action mechanism of coral materials and the shortcomings of the research on the modified treatment methods and dynamic mechanical properties of coral concrete are also summarized,which can provide reference for the subsequent research.
