Abstract: The meChanical Performance of common concrete can be improved by adding other compositions,such as steel fiber,admixture to it,and the light-weight and high strength members can be obtained.The optimum mix of F.C.high strengthconcrete is presented in this paped based on the indoor test and theoretical analysis.

Key words: F.C.high strength concrete, aggregate grading, strength of break, mix

摘要： 在混凝土中掺入一定量的钢纤维（包括钢丝网、钢筋）、外掺剂等可以改善混凝土的力学性能，使构件达到高强轻质的目的．本文通过室内试验和理论分析，提出了F、C高强混凝土的最佳配合比．
