摘　　要：试验研究了粗集料的最大粒径、种类、粒形以及细集料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。结果表明，在本文研究条件下，对混凝土强度而言，存在最佳的最大集料粒径、针片状含量以及砂率。：In this paper the four aspects of aggregate have been discussed as following：1）the category of aggregate；2）the maximum dimension；3）the shape and surface texture of aggregate and 4）fine aggregate．Then some performances of high－strength and high－performance concrete have been investigatedsuch as the compressive and tensile strengththe elastic modulus． Based on the experimerts and discussionsit is concluded that a optimum aggregate dimensiona optimum value of the content of needle－form in the aggregateand a sand ratio is existed under the giver situtation of the paper．
