摘要：通过盐池浸泡试验研究了非饱和条件下碱激发矿渣砂浆的介质传输机理，分析了不同激发剂和粉煤灰掺量对碱激发矿渣砂浆中水分和氯离子传输性能的影响。结果表明：水玻璃激发矿渣砂浆的毛细吸水系数较小，强度较高；非饱和条件下，碱激发矿渣砂浆的氯离子传输性能显著低于普通水泥砂浆；水玻璃激发矿渣砂浆的表观氯离子扩散系数较NaOH激发矿渣砂浆略高。 Abstract: The medium transmission mechanism of alkali activated slag mortar under unsaturated condition was studied by salt pool immersion test, and the effects of different activators and fly ash contents on the moisture and chloride ion transport performance of alkali activated slag mortar were analyzed. The results show that the capillary water absorption coefficient of slag mortar activated by water glass is small and the strength is high. Under the unsaturated conditions, the chloride ion transport performance of alkali activated slag mortar is lower than that of ordinary cement mortar. The apparent chloride ion transport coefficient of slag mortar activated by water glass is slightly higher than that of slag mortar activated by NaOH.
