海砂中氯离子含量是影响海砂在建筑工程中使用的主要因素。为测试现行的海砂测试方法的准确性,本文采用不同的试验方法进行海砂氯离子的测试。研究了常温浸泡时间、水浴浸泡时间和浸泡温度对海砂氯离子测试结果的影响,结果表明:延长浸泡时间和升高水浴的温度对氯离子的析出都有促进作用。 Chloride ion content in sea sand is the main factor affecting the use of sea sand in construction. In order to test the accuracy of the current sea sand test method, different test methods were used to test the sea sand chloride ion. The effects of soak time at room temperature, immersion time and immersion temperature on the test results of seawater chloride were studied. The results show that prolonging immersion time and increasing the temperature of water bath can accelerate the precipitation of chloride ions.
