摘要：

本文研究了以普通品质的粉煤灰，在粉煤灰掺量为２５ ％ 以上，水泥用量小于３００ｋｇ／ｍ３ 的情况下，可配制出２８ 天强度达６０ Ｍ Ｐａ 以上，且工作性能好，耐久性高的高性能混凝土，并在华南沿海某港口工程中进行了现场应用

This paper introduces the investigation and application of a flyash concrete with a well workability, high performance, high durability. The flyash concrete was made of an ordinary flyash with content of more than 25 percent and cement content less than 300kg/m 3. The strength of the flyash concrete can be greater than 60MPa at the age of 28 days. The application of the flyash concrete was conducted in the field of the port works of Huanan coastal area.
