利用当地工程上实际使用的原材料，采用粉煤灰单掺、粉煤灰与矿粉双掺配制了C20、C30、C40、C50等不同强度等级的泵送混凝土；试验研究了自然养护条件下7～180 d不同龄期的抗压强度和碳化深度；分析总结了单掺、双掺、不同掺量等因素对不同龄期、不同强度等级混凝土的强度和碳化的影响规律。

Using the raw material used in local projects actually,with coal ash single-doped and the coal ash double-doped with mineral powder,we have made up the different strength grades of pump concrete such as C20,C30,C40,C50;the research also studied that the compressive strength and the carbonation depth of the concrete during different ages: from 7 days to 180 days under the condition of nature curing;the research summarized that the rule of the influence of different factors such as single-doped,double-doped and different mixing amount on strength and carbonation of the concrete of different ages and different strength grades.
