摘要
为研究不同硅灰掺量下珊瑚混凝土的力学性能变化规律,本试验通过对硅灰增强珊瑚混凝土的立方体抗压强度、劈裂抗拉强度进行研究,确定硅灰的最佳添加量,为进一步研究硅灰增强珊瑚混凝土其它性能及应用提供参考.试验结果表明：替代率为20％～30％的硅灰可有效提高珊瑚混凝土抗压强度及劈裂抗拉强度.
To study the changes of the mechanical properties of coral concrete under different silica fume content,the experiment is researched on the cube compressive strength and splitting tensile strength of silica fume reinforced coral concrete,to determine optimum amount of silica fume and provide a reference for further study of other properties and applications of silica fume reinforced coral concrete.The test results showed that：the substitution rate of 20％ to 30％ silica fume can significantly improve the coral concrete＇s cube compressive strength and splitting tensile strength.
