摘　　要：不同种类的混凝土对环境和人类健康有不同程度的有害影响,应用生命周期评价,分析产品从生产、使用到最终处理处置过程中对环境的影响。根据不同的评价目的,选择有针对性地特征化模型,赋予权值并得到结果。结果表明:掺有粉煤灰的混凝土优于普通的硅酸盐水泥混凝土,对环境的影响小。The concrete of different materials has varying degrees of adverse effects on the environment and human health,it is analyzed the use of product and the list of terminal handling stage by life cycle assessment method.The results are got by selecting a targeted feature model according to the different purposes of evaluation and weighting the data.The last results show that the fly ash concrete are better than the cement concrete,which has smaller impacts on the environment,such as the formation of carcinogens.
