摘 要:针对目前对珊瑚碎屑混凝土的力学机理尚不清晰这一问题,对不同龄期和水灰比的珊瑚混凝土试块进行了试验研究。试验结果表明,珊瑚混凝土具有早强、快硬的特点;同时,当水灰比减小到一定程度后,单纯减小水灰比并不能明显提高珊瑚混凝土的抗压强度。本文从材料特性、界面特性以及龄期和水灰比等方面着手,对珊瑚混凝土的强度特性作了详细分析,并介绍了珊瑚混凝土的破坏形态,从而可为珊瑚碎屑应用于海岛混凝土工程提供一定的参考依据。
Abstract: Currently, the mechanical mechanism of coral debris concrete is not well understood, so the research on coral concrete test block in different age and water cement ratio is carried out. The test results show that coral concrete has the characteristics of fast strengthening and hardening, and when the water cement ratio decreases to a certain extent, simply reducing the water cement ratio could not result in obvious additions of compressive strength of coral concrete. From the aspects of material properties, interface properties,age and water cement ratio, the strength characteristics of the coral concrete are analyzed in detail, and the failure pattern is introduced, which can provide reference for application of coral debris in island concrete engineering.
