摘　　要：本文试验分析了集料的种类、最大粒径与级配、粒形与表面特征、针片状骨料含量以及砂率对高强高性能混凝土力学性能，如抗压强度、抗拉强度和弹性模量等的影响。根据试验和分析，可以作如下结论：在本文所设定的情况下，存在最佳的最大集料粒径、最佳砂率以及最优针片状含量等。This paper study and discusses the influence of the influence of the category of aggregate,the maximum dimension,the grade of a ggregate,the shape and surface texture of aggregate,the shape and surface textur e of aggregate,the ratio of corse aggregate and fine aggregate,and the sand rat io on mechanical performances of high sytrength and high performance concrete ，such as the compressive and tensile strength,the elastic modulus.Based on the experiments and discussions,it is concluded that a optimum maximum dimension and a sand-ratio,a optimun content of coarse aggregate existed under the given sit uation of the paper.
