摘　　要：粉煤灰作为一种工业废料在道路建设中得到广泛的应用,尤其是在提倡"节能减排"理念的今天,粉煤灰的应用能带来极大的经济与社会效益。海排粉煤灰与石灰粉煤灰相比,最大的区别就是其中含有大量的氯离子。了解有关氯离子对粉煤灰石灰土性能的影响的理论研究。然后通过试验的方法来得出氯离子对海排粉煤灰石灰土的强度和抗冻性的影响。结果表明,含有适量氯离子的海排粉煤灰是能够应用于道路建设中的。Fly ash has been more widely used in road construction as an industrial waste, especially in the promotion of ＂energy saving＂ today. The application of fly ash can bring great economic and social benefits. The biggest difference between fly-ash-flushed-by-seawater and fly ash is that it contains a large quantity of chloride ion. Firstly we know about the chlorine ion effect the performance of fly-ash-flushed- by-seawater from the theoretical study. Through the experimental methods to draw the chlorine ion affect the strength of fly-ash-flushed-by-seawater and frost resistance. The results show that the fly-ash-flushed- by-seawater which contain appropriate chloride ion can be used in road construction.
