摘　　要：本文研究了粉煤灰复合超细粉（ＰＦＡＣ）的技术性质。ＰＦＡＣ的粉体效应赋予混凝土一系列的高性能，以３０％～７０％的ＰＦＡＣ等量取代水泥可配制出Ｃ６０～Ｃ９０的高性能混凝土（ＨＰＣ），并具有良好的和易性、耐久性、力学性能、坍落度经时损失小。试验结果表明，大掺量的ＰＦＡＣ配制ＨＰＣ是可行的，这对于提高ＨＰＣ的绿色度，使之成为可持续发展的材料至关重要。This paper discuss the technique characteristic of Ultra pulverized Fuel Ash Composite Powder (PFAC). The powder effect of PFAC endows concrete with a series of high performance. The cement replaced by 30%～70% PFAC in quantity may prepare C60～90 Concrete, which has excellent workbility, durability, mechanical properties and less slump loss. The test results demonstrate that it is feasible to prepare the concrete containing a large quantity of PFAC, hich is important to increase the green degree of HPC and to make it become a lasting development materials.
