摘要

【目的】远海岛礁作为海洋资源开发的重要支撑平台，就地取材制备珊瑚混凝土对岛礁工程建设有重要意义。为了解决珊瑚混凝土强度低、脆性大、耐久性及和易性较差等问题，需要对珊瑚混凝土进行改性增强，以满足应用于高层次的建筑结构甚至防爆抗震领域。【方法】基于文献调研，综述了珊瑚骨料特性、珊瑚混凝土力学性能、改性增强技术、耐久性能和高强高性能珊瑚混凝土开发的研究进展。【结果】结果显示：骨料强度低、孔隙率大和海盐浓度高等天然缺陷制约着珊瑚混凝土性能的发展；除骨料自身外，配合比设计中的胶凝材料、外加剂、纤维制品等均对珊瑚混凝土性能有重要影响。【结论】结果表明：胶凝材料、外加剂、优化配合比、采用酸溶液或有机溶液处理骨料、掺入纤维等技术方法能有效提升珊瑚混凝土力学性能；暴露时间和矿物成分能改善珊瑚混凝土的抗渗能力；碳化与环境相关，并非所有矿物成分都利于提高抗碳化性能；考虑水泥类型、矿物成分有利于提升混凝土的抗硫酸盐性能；高孔隙率和骨料缺陷是制约强度发展的关键问题，采用低气压搅拌或地聚物基可制备高强/高性能珊瑚混凝土。还探讨不同改性增强技术的优缺点及效果，并对前沿的高强/高性能珊瑚混凝土材料和结构研究领域进行展望，可为后续研究方向提供参考。

Abstract

[Objective] As an important supporting platform for marine resources development, it is of great significance to prepare coral concrete in the construction of the island reef project. In order to solve problems such as low coral concrete strength, high brittleness, durability and poor and pronounced problems, the coral concrete needs to be modified to increase to meet the high-level building structure and even explosion-proof seismic fields. [Methods] Based on literature surveys, the research progress of coral aggregate characteristics, coral concrete performance, modified enhancement technology, durability and high-strength and high-performance coral concrete development research progress. [Results] The result showed that the strength of the aggregate aggregate, the high pore rate, and the high concentration of the sea salt restricted the development of coral concrete performance; except for the ingredients itself, the cohesive materials, external agents, fibrous products, etc. in the design of the than the design of the than the design of the corals The performance of concrete has an important impact. [Conclusion] Gel condensate materials, external agents, optimized coordination ratio, use of acid solution or organic solution to treat aggregate, incorporate fiber and other technical method can effectively improve coral concrete performance; exposure time and mineral component can improve the anti-osmotic anti-penetration of coral concrete Capability; carbonization is related to the environment, not all mineral components are conducive to improving the resistance of carbon; considering the type of cement and mineral components that are conducive to improving the anti-sulfate performance of concrete; Low pressure stirring or ground polymer can prepare high-strength/high-performance coral concrete. Research findings also explores the advantages and disadvantages and effects of different modified enhanced technologies, and looks forward to the field of high-strength/high-performance coral concrete materials and structural research on cutting-edge at front, which can provide a reference for subsequent research directions.
