中文摘要：

采用三种工业废渣,配制水泥净浆试件,试验研究了标准养护和自然养护条件下,水泥制品中重金属元素在3d、7d和28d的溶出性能,并采用重金属元素的可溶出量指标评价了水泥制品的环境安全性。结果表明,水泥制品造成土壤重金属污染的风险较小;粉煤灰水泥制品和矿渣水泥制品在自然水环境下是安全的;炉渣水泥制品可能会造成水环境的Cr、Zn污染。各重金属元素溶出率的排列次序为：Zn〉Cr〉Cu〉Cd〉As≈Pb。随养护龄期的延长,重金属元素的溶出率减小。与标准养护相比,自然养护条件下水泥制品中重金属元素的溶出率增大。

英文摘要：

Three kinds of industrial wastes were used to make the cement paste specimens. Leaching of heavy metals from the cement products exposed to the standard curing and the natural curing was experimentally researched at curing ages of 3d, 7d and 28d. The leaching index of heavy metals was applied to assess the environmental safety of cement products..The results show that the cement products may not cause the heavy metals pollution to soils. Fly ash cement products and Slag cement products are safe for the water environment; while the municipal solid waste incineration fly ash cement products may cause the Cr and Zn pollution to the water environment. The leaching ratios of heavy metals are Zn〉 Cr〉Cu〉Cd〉As ≈Pb. The leaching ratios of heavy metals decrease with the curing age. Compared with the standard curing, heavy metals have larger leaching ratios from the cement products exposed to the natural curing.
