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 studies the technical properties of fly ash composite ultrafine powder (PFAC). The powder effect of PFAC gives a series of high performance to the concrete. It replaces cement with 30% to 70% of PFAC to prepare C60-C90 high performance concrete (HPC) with good workability and durability. Mechanical properties, slump loss over time. The experimental results show that high-volume PFAC formulation of HPC is feasible, which is essential for improving the green degree of HPC and making it a sustainable material.
