摘　　要：文中分析了均匀密实性对混凝土的高性能化的影响;通过计算,表明了混凝土的砂浆率、骨料用量及用水量与均匀密实性之间的关系;提出了减水剂的"饱和掺量"和"临界掺量"两个概念。This article analyses the influence of uniform compactness on the high performance of concrete.Through calculation,the relationship between the mortar rate,aggregate amount and water consumption of concrete and uniform compactness is shown.Put forward two concepts of"saturated dosage"and"critical dosage"of water reducing agent.

关 键 词：高性能混凝土 密实性 净浆体积 最低胶材量
