摘　　要：通过实验 ,研究粉煤灰及减水剂对高性能混凝土工作性及强度的影响。实验结果表明 :掺水泥用量 33%的优质粉煤灰时 ,可配制出坍落度 >2 0 0 mm,扩展度 >6 0 0 mm,2 8天强度达 85 .6 Mpa的高性能混凝土。The paper discussed the influence of flyash and water reducing agent on the workability and strength of high performance concrete based on the experiment And the result showed that the high performance concrete may be compounded with the collapsing degree>200mm, the extending degree>600mm and the compressive strength of 85 6 MPa within 28 days by adding 33% of high quality flyash instead of partial cement
