研究了冻融循环对尼龙纤维混凝土（体积掺量分别为０．５％，１％，１．５％）和基准混凝土的动态弹性模量与质量变化的影响，以及纤维砂浆力学性能随冻融循环次数的变化规律．试验结果表明：纤维混凝土３００次冻融循环时的质量及动态弹性模量损失远远小于基准混凝土，纤维砂浆的抗折强度、抗压强度损失远远小于基准砂浆．尼龙纤维水泥基复合材料抗冻性能的提高，部分原因与尼龙纤维的引气作用有关
The effects of freeze-thaw cycles on the dynamic elastic modulus and mass change of nylon fiber concrete (volume content of 0.5%, 1%, 1.5%, respectively) and the reference concrete were studied, as well as the mechanical properties of the fiber mortar with freeze-thaw cycles. The law of the number of cycles. The test results show that the loss of mass and dynamic modulus of elasticity in the 300 cycles of freeze-thaw cycles of fiber concrete is much smaller than that of the reference concrete. The loss of bending strength and compressive strength of the fiber mortar is much smaller than that of the reference mortar. The improvement of frost resistance of nylon fiber cement-based composites is partly related to the bleed air effect of nylon fibers.
