摘要：

This paper presents the fluidity and compressive strength of concrete containing ultrafine fly ash composite (UFAC). The experimental results indicate that UFAC can improve the fluidity and compressive strength of concrete at 30-70% replacement of cement. UFAC concrete had been prepared with a larger slump, higher compressive strength, lower slump loss and lower drying shrinkage ratio. (C) 2000 Elsevier Science Ltd. All rights reserved.
