| 摘要: |
| 在研究碎石粒形特性对砼性能的影响及粒形评价指标的基础上，提出了对碎石粒形进行质量分级的建议。同时对碎石砼的一些基本特性进行了具体分析，证明碎石砼更适合于在高强度、高流态的砼工程中应用。 |

| Basic Characteristics of Broken Stone Concrete |
|
|
| Abstract: |
| On the basis of studying influences of broken stone granular behavior on concrete property and granular evaluation index,this paper puts forward a proposal that broken stone granular should be graded according to its quality.Moreover,some basic characteristics of broken stone concrete are analysed,which proves broken stone concrete is more suited to high-strength,high-flow concrete works. |
| Key words: broken stone,broken stone concrete,granular behavior,concrete strength |
