摘要：
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.
