摘　　要：通过恰当的低水胶比、掺加活性细掺合料和混凝土高效外加剂 ,研制成粉煤灰高性能混凝土。介绍了粉煤灰高性能混凝土的配制及性能 ,并对活性细掺合料提高混凝土的强度、抗渗性及抗冻性的机理进行了分析研究。The fly ash high performance concrete is developed by adding active fine admixture and concrete high efficient additives under proper low water/binder ratio. This paper introduces preparation and properties of the fly ash high performance concrete. The mechanism of the active fine admixture to increase the strength, impermeability and freeze resistance of concrete was analyzed and studied.
