摘　　要：为分析水灰比和粉煤灰掺量对水泥砂浆的水分传输性能影响,文中通过湿润、干燥和干湿循环试验,测试并分析水泥砂浆的吸水系数、失水系数和水分含量的变化。结果表明较低水灰比或掺入适量的粉煤灰可以降低水泥砂浆的吸水系数、失水系数以及水分变化量,增强水泥砂浆对水渗透和流失的抵抗能力。研究结果可为水泥砂浆耐久性提供参考。Water cement ratio and dosage of fly ash on the properties of cement mortar water transport are investigat-ed through the wet,dry and wet cycle experiments,in which the cement mortar suction/water loss coefficient and the change of moisture content are analyzed.The results show that water loss coefficient and the change of water uptake can be reduced by lowing water cement ratio and adding the right amount of fly ash cement mortar,which enhances the cement mortar on the water infiltration and erosion resistance,providing the reference for the durability of ce-ment mortar.
