本文尝试使用电导率测试法取代氯离子含量测定法判定细骨料是否为海砂。一系列的试验结果表明,海砂与洁净天然砂的电导率存在显著差异,砂中含泥量和测试温度均对电导率测试结果有所影响,但都不足以影响对细骨料是否为海砂的判定,电导率测试法可以作为一种过程控制手段,判断细骨料是否为海砂。 This paper attempts to use the conductivity test instead of chloride content determination of fine aggregate is sea sand. A series of test results show that the conductivity of sea sand and clean natural sand there is a significant difference, clay content in the sand and the test temperature have an impact on the conductivity test results, but not enough to affect the fine aggregate is the sea Determination of sand, conductivity test method can be used as a process control means to determine whether the fine aggregate sea sand.
