摘　　要：为了改善粉煤灰自密实混凝土的性能,本文通过试验研究了自制功能组分对粉煤灰自密实混凝土工作性、抗压强度和抗碳化性能的影响。结果表明,在满足相同工作性的条件下,掺入两种功能组分可以降低粉煤灰自密实混凝土的用水量,并提高混凝土早期强度和抗碳化能力。For the purpose of improving the performance of the self-compacting fly-ash concrete,this paper studies the effects of homemade functional components on its workability,compressive strength and carbonation resistance.The results indicated that mixing two function components can reduce water consumption,improve early strength and carbonation ability of the concrete.

关 键 词：自密实混凝土 功能组分 工作性 抗碳化性能
