随着近年来电厂循环硫化床脱硫工艺的广泛应用,电厂的另一个污染源脱硫煤渣随之产生。因此,积极开展脱硫粉煤灰在道路工程中应用的研究是推动粉煤灰综合利用工作的重要措施之一。文章将大连两家电厂脱硫工艺产生的粉煤灰加入到二灰碎石路面基层材料中,进行了室内击实试验及强度试验,为脱硫粉煤灰在路面基层中的应用提供依据。
With the widespread application of desulphurization process of circulating sulphide beds in power plants in recent years, desulphurization of cinder is another source of power generation. Therefore, the active application of desulfurized fly ash in road engineering is one of the important measures to promote the comprehensive utilization of fly ash. In this paper, fly ash from the desulfurization process of two power plants in Dalian is added into the base material of lime-fly ash gravel pavement. The indoor compaction test and strength test are carried out to provide the basis for the application of desulfurized fly ash in the pavement base.
