In order to solve the problems of low strength and brittle failure of plain ice when used as building material, ice was reinforced with primary pulp fibers. The fiber reinforced ice (FRI) was researched with uniaxial compressive tests under 20 working cases to investigate the effects of temperature (− 20 °C, − 15 °C, − 10 °C, − 5 °C) and fiber content (0%, 1%, 2%, 4%, 6%). The results show that the strength of FRI is about 4 times of the plain ice and the ductility is much better than plain ice. The mechanical properties of FRI exhibited temperature sensitivity and fiber content sensitivity. Based on the test results, the statistical models of peak strength, peak strain and modulus of elasticity were established, and the uniaxial constitutive models of plain ice and FRI were established. Material design values are suggested by reliability analysis. The conclusions can contribute to the application of FRI materials in buildings.

单轴压缩下纤维增强冰的性能

为了解决普通冰作为建筑材料强度低、脆性破坏的问题,用原生浆纤维对冰进行了增强。在 20 个工况下通过单轴压缩试验研究了纤维增强冰 (FRI),以研究温度 (- 20 °C、- 15 °C、- 10 °C、- 5 °C) 和纤维含量 (0%) 的影响、1%、2%、4%、6%)。结果表明,FRI的强度约为普通冰的4倍,延展性远优于普通冰。FRI 的机械性能表现出温度敏感性和纤维含量敏感性。根据试验结果,建立了峰值强度、峰值应变和弹性模量的统计模型,建立了普通冰和FRI的单轴本构模型。通过可靠性分析建议材料设计值。
