Abstract：In this paper，based on the optimal selection of the mix proportion.a kind of high-performance PFA concrete，with a little dosage of cement (C≤165 kg/m3)，the PFA content being above 70%,HPC with high workability (slump:24 cm)whose strength is above 80 MPa，has been obtained. The experimental results have been indicated that the High-Performance PFA Concrete has such advantages as high fluidity，small percentage loss of slump，high modulus of elasticity，small drying shrinkage,high durability,high Green and so on. Its application has been proved successfully in abrupt slope roof structure in student's third dining hall of Changsha Railway University.
