摘　　要：随着我国电力事业的发展,粉煤灰的排放量也在逐年增加,以至造成了严重的环境污染。粉煤灰和减水剂双掺混凝土,不仅能大量利用粉煤灰,节约水泥,而且能提高工程质量和降低成本。本文以C 30为例,分析了粉煤灰双掺混凝土和普通混凝土耐久性指数,论证了粉煤灰双掺混凝土工程应用的可行性。With the development of our country power industry, it is polluted seriously with the increase of discharge quantity of fly ash. Fly ash and plasticizer co - dope concrete not only uses fly ash more, saves cement, but also increases quality of concrete construction and reduce cost. Taking C30 concrete for example, analysis the durability index of common concrete and co - dope concrete, and proved the engineering application feasibility of fly ash for co - dope concrete.
