| 摘 要： | 火电厂脱硫技术的应用对改善大气环境具有重要意义。粉煤灰中硫的存在对二灰混合料的强度是有贡献的，但过量的SO3对二灰混合料体积安定性将产生重要影响。通过大量试验，对SO3在二灰碎石基层中的作用进行深入研究，对低质粉煤灰的推广应用具有重要参考价值。

| Abstract: | The application of sulfur removal technology shows significance to improvement of atmospheric environment.Although the existence of sulfur in flyash contributes to strength of lime-flyash mixture,excessive SO3 will produce important effect on volume invariability of lime-flyash mixture.With the help of large quantity of tests,this paper deeply investigates the effect of SO3 in lime-flyash-gravel roadbed,which presents significant reference for popularization,and application of low-quality flyash. |
