通过试验测定并分析了掺有纤维、粉煤灰的水泥砂浆的扩散系数，研究了在相同水灰比情况下，不同掺合料对砂浆抗氯离子侵蚀能力的影响。结果表明，不同的掺合料均能提高水泥砂浆抗氯离子侵蚀能力，对氯离子扩散系数衰减速率有较大的影响；砂浆的氯离子扩散系数均随着侵蚀时间的延长而降低。

According to a series of test,diffusion coefficients of cement mortar mixing fiber and fly ash are analyzed.Under the similar water cement ratio,effects of the different admixtures on chloride ion corrosion resistance of mortar are studied.Analysis results indicate that the admixtures can improve the ability to counter chloride diffusion of cement mortar ,and which have the great influence of the atten-uation rate of chloride ion diffusion.All of the chloride ion diffusion coefficients are decreasing with the erosion time prolonging.
