Abstract

Coral aggregate has been widely used for island construction because of its local availability. However, the addition of coral aggregate exaggerates the brittle nature of cement-based materials under dynamic loading. In this study, polyvinyl alcohol (PVA) fiber was used to improve dynamic mechanical behavior of seawater coral mortars (SCMs). The effects of coral aggregate and PVA fiber on the workability, static mechanical strengths, and dynamic mechanical behavior of fiber-reinforced SCMs were investigated. Results showed that the workability of the SCM decreased with increasing coral aggregate replacement rate and PVA fiber content. Mechanical strengths of the SCM increased with increasing PVA fiber content, but decreased with increasing coral aggregate replacement rate. Dynamic mechanical behavior at varying coral aggregate replacement rates was analyzed by combining dynamic mechanical analysis and micro-scale elastic modulus experiment. With increasing coral aggregate replacement rate, the storage modulus, loss factor, and elastic modulus of the interfacial transition zone in the SCM decreased. Nevertheless, with the incorporation of PVA fibers (1 vol.%), the storage modulus and loss factor were improved dramatically by 151.9 and 73.3%, respectively, compared with the reference group. Therefore, fiber-reinforced coral mortars have a great potential for use in island construction, owing to the excellent anti-vibrational performance.

摘要

珊瑚骨料因其在当地易于获取而被广泛用于岛屿建设。然而，添加珊瑚骨料会加剧水泥基材料在动态荷载作用下的脆性。在本研究中，使用聚乙烯醇（PVA）纤维来改善海水珊瑚砂浆（SCM）的动态力学性能。研究了珊瑚骨料和PVA纤维对纤维增强SCM的工作性、静态力学强度和动态力学性能的影响。结果表明，SCM的工作性随着珊瑚骨料替代率和PVA纤维含量的增加而降低。SCM的力学强度随着PVA纤维含量的增加而提高，但随着珊瑚骨料替代率的增加而降低。通过结合动态力学分析和微观尺度弹性模量试验，分析了不同珊瑚骨料替代率下的动态力学性能。随着珊瑚骨料替代率的增加，SCM中界面过渡区的储能模量、损耗因子和弹性模量降低。然而，与参考组相比，掺入PVA纤维（1体积%）后，储能模量和损耗因子分别显著提高了151.9%和73.3%。因此，由于具有优异的抗振性能，纤维增强珊瑚砂浆在岛屿建设中具有巨大的应用潜力。
